Description

A high-efficiency hoisting device for fully mechanized mining supports

technical field

The utility model relates to the field of fully mechanized mining equipment in coal mines.

Background technique

With the improvement of mechanization level requirements for coal mining, fully mechanized mining equipment with high mechanical automation has been widely used in coal mining in my country. Fully mechanized mining is the abbreviation of comprehensive mechanized automatic coal mining, mainly including coal shearer, scraper conveyor, fully mechanized mining hydraulic support and other equipment. The three-machine matching is the core of fully mechanized mining equipment. Generally speaking, the function of the shearer is to collect coal from the coal wall, the transport plane is to transport the coal out, and the function of the fully mechanized mining support (that is, the hydraulic support) is to cover the working face to prevent the mine from collapsing and gangue The occurrence of accidents such as falling and hurting people. The stable construction of fully mechanized mining support is a prerequisite for the normal operation of fully mechanized mining equipment, but due to its heavy weight and large volume, the handling of fully mechanized mining support has always been a problem, especially in narrow underground roadways. The transportation of fully mechanized mining supports not only consumes a lot of manpower and material resources, but also slow transportation also affects the advancing speed of fully mechanized mining faces, which undoubtedly greatly affects the economic benefits of coal mining enterprises.

In the prior art, as described in the patent document 201420533363.7, there is a method of anchoring the hoisting device on the mine roof and using the contraction ability of the bracket itself for hoisting. Although this method is fast, because the top rock structure is likely to be loose during the excavation process of the mine, the hoisting device anchored on the roof itself is not stable and there is a risk of falling off. There are also other existing technologies that adopt various equipment placed on the ground to carry out the hoisting of the fully mechanized mining support, but the weight of the equipment for hoisting the fully mechanized mining support is also relatively heavy, especially the jack used for hoisting. Although the lifting of the support can be completed, the Its own handling has become a very big problem again.

Contents of the invention

The purpose of the utility model is to provide an efficient hoisting device for a fully mechanized mining support that is convenient for transportation.

In order to achieve the purpose of the above invention, the technical solution adopted by the utility model is: a high-efficiency hoisting device for fully mechanized mining support, including a track and a flatbed truck running on the track, and hoisting columns for hoisting fully mechanized mining support are arranged on both sides of the track, The top of the hoisting column is connected with a sling and a hook, and the bottom is anchored to the ground. The hoisting column includes a column jack whose extension direction of the upper part is upward and a column jack whose extension direction of the lower part is downward, and the part between the two jacks is provided with a hydraulic cylinder toward the direction of the track, and the piston rod of the hydraulic cylinder A connecting pin is formed, and a connecting pin sleeve matched with the connecting pin is arranged on the flatbed vehicle.

Preferably, the connecting pin, the connecting pin sleeve and the flatbed are provided with corresponding fixing pin holes, and the fixing pins pass through the fixing pin holes to connect and fix the three.

Preferably, two lifting columns are arranged symmetrically on both sides of the track.

Preferably, a detachable reinforcing beam is arranged between the hoisting columns on the same side of the track.

The beneficial effects of the utility model are embodied in that not only can the fully mechanized mining support be hoisted safely and quickly, but also the device itself can be transported quickly and efficiently. Specifically, although the method of anchoring the hoisting equipment on the roof in the prior art is fast and simple, it is easy to cause safety accidents due to the loose roof structure of the mine cave. The column is hoisted to avoid similar situations. In addition, the lifting column is fixed on the flatbed truck through the connecting pin and the connecting pin sleeve, so that the device can be transported quickly.

detailed description

A kind of high-efficiency hoisting device for a fully mechanized mining support as shown in Figure 1, comprising a track 6 and a flatbed truck 1 running on the track 6, the two sides of the track 6 are provided with hoisting columns for hoisting a fully mechanized mining support, and the top of the lifting column is connected to Sling 9 and hook 10 are arranged, and the bottom is anchored with the ground. The hoisting column includes a column jack 2 whose upper part protrudes upwards and a lower column jack 3 whose protruding direction is downwards, and the part between the two jacks 2 and 3 is provided with a hydraulic cylinder facing the direction of the track 6 , the piston rod of the hydraulic cylinder constitutes the connecting pin 4, and the flatbed truck 1 is provided with a connecting pin sleeve 5 matching the connecting pin 4.

In the actual operation process, the staff anchor the hoisting column 1 firmly on the ground on both sides of the track 6. In order to improve the stability of the device, you can choose to install two symmetrically on both sides of the track 6 as shown in Figure 1. One hoisting column, of course, more can be set, depending on the actual situation. In addition, the detachable reinforcing beam 7 is arranged between the hoisting columns on the same side of the track, which can further improve the stability of the utility model. Utilize hook 10 and sling 9 to be connected with hoisting column and fully-mechanized mining support then. Then control the jack 2 to stretch out, lift the fully-mechanized mining support, push the flatbed car, and then control the jack 2 to slowly retract and put down the fully-mechanized mining support to place it on the flatbed car 1 stably. Then the flatbed truck 1 is pulled to the designated position by the winch, and the fully mechanized mining support is unloaded to get final product.

After the fully mechanized mining support is transported, when the hoisting column of the present utility model needs to be removed, the staff first pushes the flatbed truck 1 between the hoisting columns, and then places the connecting pin sleeve 5 on the flatbed truck 1 as shown in Figure 1. Standby for use, the connecting pin sleeve 5 can of course also be integrated with the flatbed cart 1, as long as it does not affect the carrying function of the flatbed cart 1. Then adjust the telescopic length of the jack 3, because the hoisting column is anchored on the ground this moment, so the connecting pin 4 can be made to reach the height matched with the connecting pin sleeve 5 by adjusting the jack 3. The connecting pin 4 is actually the piston rod part of the hydraulic cylinder. By controlling the hydraulic cylinder, the connecting pin 4 can be controlled to extend into the connecting pin sleeve 5 on the flatbed truck 1 to complete the docking. The connecting pin 4 may be circular as shown in FIG. 1 , or square or other shapes. In order to avoid rotation of the connecting pin 4 in the following transportation process, it is better to set corresponding fixing pin holes on the connecting pin 4, the connecting pin sleeve 5 and the flatbed truck 1, and the fixing pin 8 passes through the fixing pin hole to connect the three The connection is fixed. Next, the staff releases the anchor piles or anchor cables of the hoisting column on the ground. Control the jack 3 to shrink upwards, at this moment, the hoisting column will leave the ground and be hung on the flatbed truck 1 by the connecting pin 4 . The staff should pay attention to the symmetry of both sides during operation, so that the flatbed truck 1 can be more balanced. Then the staff fully shrinks the jacks 2 and 3, so that the center of gravity can be placed on the flatbed truck 1 as far as possible. Finally, the flatbed truck 1 can be pulled away by a winch. This completes the transport of the heaviest lifting column. The remaining parts can be easily dismantled and transported by workers due to their light weight.
