Description

timing belt tensioner

technical field

The invention belongs to the technical field of synchronous belt connection, and specifically refers to a synchronous belt tensioning device applied to a hoist/stacker.

Background technique

Nowadays, logistics technology has attracted more and more attention, and warehouses play a key role in the logistics system. The hoist/stacker plays a role in the handling of goods in the entire system, which is an indispensable link in the automated warehouse and the core of the entire automated warehouse technology.

The hoist/stacker is a machine component installed in the automated three-dimensional warehouse. Its main function is to lift and transport the goods to the specified height or position. The hoist/stacker drives the synchronous belt when lifting the goods. Raise and lower the loading platform. At present, the ring-shaped synchronous belt on the hoist connects the two ends of the synchronous belt together through the connection method of the clamp block, and the clamp block and the loading platform are fixed together, and the relative position of the two is changed by adjusting the bolts connecting the two. Then realize the tensioning of the synchronous belt. The defect of this structure is that the tensioning of the synchronous belt can only be adjusted after the clamp block is fixedly connected with the loading platform, and the tensioning of the synchronous belt cannot be performed before the synchronous belt is installed on the hoist. adjust. In addition, there is still a connection method in which the clamp block and the loading platform are welded together in the existing hoist. This connection method is inconvenient for personnel to install and maintain the equipment, and it is inconvenient to adjust the tension of the timing belt.

Contents of the invention

Aiming at the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a synchronous belt tensioning device with simple structure and easy installation and maintenance. It can also realize the tension adjustment of the synchronous belt installed behind the hoist.

In order to achieve the above object, a synchronous belt tensioning device of the present invention is composed of two clamping blocks, the two are connected by bolts, and the distance between the two is changed by adjusting the bolts; the clamping blocks include: the first A splint and a second splint; the first splint is a T-shaped design, and a bolt adjustment hole is provided at both ends of its transverse part to accommodate the above-mentioned bolts; a number of mounting holes are respectively provided at both ends of its longitudinal part, through which The installation hole makes the first clamping block fixedly connected with the loading platform, the longitudinal part is provided with a groove for accommodating the timing belt in the middle of the side close to the second clamping plate, and several first connection holes are respectively provided at both ends of the side; The side of the second splint close to the first splint is provided with a plurality of tooth grooves for accommodating the timing belt rack, and the two ends of the second splint are respectively provided with a plurality of second connection holes, which are connected with the above-mentioned first connection holes. Correspondingly, the two are connected by screws.

Preferably, the number of the above-mentioned tooth grooves is four or five.

Beneficial effects of the present invention:

The synchronous belt tensioning device of the present invention is simple in structure, easy to install and maintain; it can not only realize the tension adjustment of the synchronous belt installed in front of the hoist, but also can realize the tension adjustment of the synchronous belt installed in the hoist; no other adjustment parts are needed . It can be widely used in hoists, stackers and other lifting equipment.

detailed description

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

Referring to Figures 1 to 3, a synchronous belt tensioning device of the present invention is composed of two clamping blocks connected by bolts 2, and the distance between the two is changed by adjusting the bolts 2; The clamping block includes: a first splint 11 and a second splint 13;

The first splint 11 is of T-shaped design, and a bolt adjusting hole 121 is respectively provided at both ends of its transverse portion 12 to accommodate the above-mentioned bolt 2; and several mounting holes 141 are respectively provided at both ends of its longitudinal portion 14 ( There are four), the first clamping block 11 is fixedly connected to the loading platform (not shown in the figure) through the mounting hole 141, and the longitudinal part 14 is provided with a groove for accommodating the timing belt in the middle of the side near the second clamping plate 13 142, and several first connection holes 143 (four in the embodiment) are respectively provided at both ends of the side;

On the side of the second clamping plate 13 close to the first clamping plate 11, there are several tooth grooves 131 for accommodating the synchronous belt rack, and the two ends of the second clamping plate 13 are respectively provided with a plurality of second connecting holes 132, which are connected with The above-mentioned first connecting hole 141 is corresponding, and the two are connected by screws 3 .

In this embodiment, the number of the tooth slots 131 is four; in other embodiments, the number of the tooth slots can also be selected as three or five or other numbers according to the design of the timing belt 4 rack.

Place one end of the synchronous belt 4 in the groove 142 of the first splint 11, the groove 142 is completely consistent with the size of the synchronous belt, the rack of the synchronous belt is engaged in the tooth groove 131, and the first splint 11 and the second splint are connected by the screw 3 The two splints 13 are fixed to form clamping blocks; the transverse portions 12 of the two clamping blocks are arranged oppositely, and the two clamping blocks are connected by bolts 2, and the positions of the nuts on the bolts 2 are adjusted to realize the positional relationship between the two transverse portions 12, thereby realizing Adjustment of the tension of the timing belt.
