Description

Lifting device for underground mine

technical field

The invention belongs to the technical field of power machinery and relates to a lifting device for an underground mine.

Background technique

Lifting devices for underground mines are commonly used equipment for operations such as electric power, communications, transportation, municipal administration, fire protection, rescue, building construction, maintenance and repair. With the vigorous development of the current national economy, the demand for hydraulic lifts is rising rapidly. However, the existing hydraulic lifts have defects such as poor stability, low reliability, uneven force, etc., which limit the use of the hydraulic lift, especially when rescue and underground work are prone to secondary accidents.

Contents of the invention

The object of the present invention is to provide a lifting device for an underground mine; the lifting device has good stability and high reliability, and is evenly stressed during use, thereby improving its safety performance during use.

The purpose of the present invention is solved by the following technical solutions:

This underground mine lifting device includes a base, on which a fork support is arranged, the middle part of the fork support is connected by a pin connection structure, a hydraulic device is arranged on the fork support, and a lifting platform is provided above the fork support; The two outriggers on the same side of the fork-type support are respectively fixedly connected to the lifting platform and the base, and the outriggers on the other side of the fork-type support are respectively connected to the slider structure.

Furthermore, the present invention is characterized in that:

There are two slider structures, which are respectively fixed above the base and below the lifting platform.

The pin-shaft connection structure includes a support plate, a needle bearing is arranged on the support plate, and a retaining ring is arranged outside the needle bearing.

Wherein the slider structure includes a slider, which provides a guide rail for the slider to slide.

Wherein the slider structure also includes a bearing that limits the sliding of the slider.

The contact surface between the slider and the guide rail is a drum-shaped structure composed of rollers.

The beneficial effects of the present invention are: the hydraulic device pushes the opening and closing of the fork support to realize the expansion and contraction of the distance between the lifting platform and the base, thereby realizing the lifting function of the device; the fork support is stretched and slid by adopting a slider structure. The device has a simple structure and low manufacturing cost. Since the entire base is in contact with the ground, the device is uniformly stressed during use, has good stability, high reliability, and good safety performance during use.

Furthermore, the pin-shaft connection structure of the slider can convert the force into the rolling of the bearing by providing the needle bearing, which alleviates the problem of force concentration.

Furthermore, the bearing can not only restrict the sliding block from sliding out of the guide rail, but also provide installation of the guide rail. At the same time, a rolling method is adopted between the slider and the guide rail. This sliding method will not cause a large vibration of the lifting platform during the rolling process of the slider, and can reduce the point stress of the pin connection structure.

detailed description

The present invention is described in further detail below in conjunction with accompanying drawing:

The invention provides a lifting device for an underground mine, as shown in Figure 1, comprising a base 1, a fork support 6 is arranged on the base 1, and a lifting platform 4 is arranged above the fork support 6; wherein the fork support 6 is The two support rods are combined in a criss-cross manner, and the central position of the fork support 6 is movably connected through the pin connection structure 5; the outriggers on the same side of the fork support 6 are fixedly connected to the lifting platform 4 and the base 1 respectively, and the fork support 6 The legs on the other side of the support 6 are respectively connected to a slider structure 2 , and the two slider structures 2 are respectively arranged below the lifting platform 4 and above the base 1 .

As shown in Figure 2, the pin shaft connection structure 5 support plate 9, the support plate 9 is provided with a needle roller bearing 8, the needle roller bearing 8 is arranged on the periphery of the pin connecting the fork support 6, and the outer side of the needle roller bearing 8 is provided with retaining ring7.

As shown in Figure 3, the slider structure 2 includes a slider 10, a guide rail 11 is provided below the slider 10 to provide its rolling slide, and the two ends of the guide rail 11 are provided with supports 12 to prevent the slider 10 from sliding out of the guide rail 11; The slider 10 is in contact with the guide rail 11 on four sides, wherein the contact surface between the slider 10 and the guide rail 11 is a drum-shaped structure composed of rollers.

The working principle of the present invention is: first put down the lifting platform 4, that is, zoom the hydraulic device 3 to the shortest, so that the fork support 6 is in a contracted state; then transfer the workers or materials to the lifting platform 4, and then slowly move the hydraulic device 3 Elongation, while the fork support 6 slides through the slider structure 2, and the fork support 6 is in an elongated state, and its height is in a suitable position.
