Background technique

The joint filling machine is mainly used for surface crack treatment of asphalt pavement, cement pavement and site, and it is used in conjunction with slotting machine and vehicle-mounted hoisting machine. The existing large-scale vehicle-mounted joint filling machines are generally integrated with the carrier vehicle and the joint filling machine. When the joint filling machine is not working, the carrier vehicle can only be parked and not used, and the scope of use of the carrier vehicle is very limited; The car and the seam filling machine are separated. In this way, when the seam filling machine is not working, the truck can be used alone. However, the loading and unloading of the seam filling machine requires a crane, and the loading and unloading process is complicated, difficult and time-consuming. On the other hand, the loading and unloading of the seam filling machine can use the jack as the lifting mechanism, and the lifting height of the ordinary jack is limited to the stroke of its transmission component. When a larger lifting height is required, only a larger stroke can be replaced. Lifting mechanism, its scope of use is limited.

The lifting height of the lifting mechanism is increased by a manual height adjustment mechanism in addition to the stroke of the transmission component itself, and the actual lifting height = the stroke of the transmission assembly + the selectable height of the height adjustment mechanism, which improves the range of the height adjustment of the lifting mechanism.

The above-mentioned purpose is achieved through the following technical solutions:

A lifting mechanism for loading or unloading a vehicle-mounted seam filling machine, including a jack device. The jack device includes a lifting part and a bracket. The lifting part is supported by the bracket and can move up and down relative to the bracket. It is characterized in that: There is a height adjustment mechanism, the height adjustment mechanism includes a base, the base is provided with a number of adjustment holes arranged up and down, the bottom of the bracket is provided with positioning holes, the bracket can slide up and down relative to the base, and the positioning holes can be selected when the bracket slides The ground communicates with any adjusting hole, and the positioning pin is inserted into the positioning hole and the adjusting hole communicated with the positioning hole.

The above technical scheme can be further improved through the following measures:

The adjustment holes are arranged at equal intervals.

The lifting part includes a lifting sleeve, and the lifting sleeve is sleeved on the outside of the bracket.

A detachable cross bar is arranged on the lifting sleeve.

A sleeve is arranged on the base, an adjustment hole is arranged on the peripheral wall of the sleeve, and the bracket is slidably inserted into the sleeve.

The bracket is in the shape of a square column, and the cross section of the sleeve is square to match the bracket.

There are two rows of adjusting holes on the sleeve, which are respectively located on the two side walls of the sleeve. There are two positioning holes on the bracket, and one positioning hole corresponds to a row of adjusting holes.

Compared with the prior art, the utility model has the following advantages:

(1) The lifting mechanism includes a jacking part and a bracket. The jacking part is supported by the bracket and can move up and down relative to the bracket. A height adjustment mechanism is provided at the bottom of the bracket. The height adjustment mechanism includes a base, a base There are a number of adjustment holes arranged up and down on the top of the bracket. There is a positioning hole at the bottom of the bracket. The bracket can slide up and down relative to the base. When the bracket slides, the positioning hole can be selectively communicated with any adjustment hole. In the adjustment hole connected to the positioning hole, the actual lifting height of the lifting mechanism = the stroke of the transmission component + the optional height of the height adjustment mechanism, so as to increase the adjustment height range of the lifting mechanism, and the height adjustment mechanism can be adjusted manually. Easy to adjust;

(2) There is a detachable cross bar on the lifting sleeve, which can be connected with the object to be lifted. For different objects to be lifted, different cross bars can be replaced, which is easy to use;

(3) The base is provided with a sleeve, the adjustment hole is provided on the peripheral wall of the sleeve, and the bracket can be slidably inserted into the sleeve, the structure is simple, and the adjustment is convenient and fast.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

As shown in Figures 1 to 3, a lifting mechanism for loading or unloading a vehicle-mounted seam filling machine includes a jack device, and the jack device includes a jacking part 1 and a bracket 2, and the jacking part 1 is supported by the bracket 2, and the inside of the bracket There is a transmission assembly, which can drive the lifting part to move up and down relative to the support 2. The structure of the lifting part, transmission assembly and support can refer to the structure of a common jack. A height adjustment mechanism is provided at the bottom of the support 2. The height adjustment mechanism includes A base 3, the base 3 is provided with several adjustment holes 31 arranged up and down, the bottom of the support is provided with positioning holes 21, the support 2 can slide up and down relative to the base 3, and the positioning holes 21 can be selectively aligned with the support 2 when sliding Any adjusting hole 31 communicates, and the positioning pin 4 is inserted into the positioning hole 21 and the adjusting hole 31 communicating with the positioning hole to fix the bracket 2 .

The adjustment holes 31 are arranged at equal intervals.

The lifting part 1 includes a lifting sleeve, and the lifting sleeve is sleeved on the outside of the bracket 2 .
