Description

Technical Field

[0001] The utility model relates to the technical field of ground rollers, in particular to a ground roller device for mines that can prevent derailment. Background Technique

[0002] Mine ground rollers are mainly used to lift heavy objects at the inclined or vertical shaft wellheads to reduce the bearing weight of the steel wire ropes. They are installed on the slopes of mine hoists and play a guiding role and a role in supporting the steel wire ropes through the combination of the roller body and the roller shaft.

[0003] However, the existing ground rollers are directly placed in the card slots. When the ground rollers rotate, the ground rollers will derail, resulting in certain potential safety hazards during the use of the ground rollers. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a ground roller device for mines that can prevent derailment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A ground roller device for mines that can prevent derailment, including a support and a ground roller body. Both sides of the support are provided with grooves. An insertion block is inserted and movably connected in the groove. A sliding groove is opened inside the insertion block. Two sliding rods are movably connected in the sliding groove. One ends of the two sliding rods are fixedly connected with clamping blocks. The two ends of the ground roller body are respectively movably connected with rotating blocks. A notch is opened inside the rotating block, and the insertion block is inserted into the notch. Grooves are opened on both inner walls of the rotating block, and the clamping blocks are clamped in the grooves. A spring is fixedly connected between the two sliding rods. Blocking components for restricting the positions of the sliding rods are provided on both sides of the support.

[0007] As a further scheme of the utility model, the blocking component includes a threaded groove opened on one side of the support. A threaded rod is movably connected in the threaded groove. A baffle is movably connected to the outside of the threaded rod. Two card slots are opened on one side of the baffle, and the card slots are inserted with the sliding rods.

[0008] As a further scheme of the utility model, guide rods are fixedly connected to the outer walls of both sides of the support, and the baffle is slidably connected with the guide rods.

[0009] As a further scheme of the utility model, a positioning column is fixedly connected in the sliding groove.

[0010] As a further scheme of the utility model, the sliding rod is slidably connected with the positioning column.

[0011] As a further scheme of the utility model, one end of the threaded rod passes through the baffle and is fixedly connected with a knob.

[0012] As a further solution of the present utility model, the baffle is in contact with the insertion block.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. Through the cooperative use of the groove and the clamping block, a stable connection is obtained between the roller body and the support, so that the roller body can rotate stably, avoiding the situation of derailment during the rotation of the roller, which may cause potential safety hazards, and improving the safety of the device.

[0015] 2. By setting the blocking component, the position of the sliding rod is restricted and fixed, preventing the device from colliding and vibrating, which may cause the sliding rod to move. Thus, the clamping block can be stably inserted into the groove, improving the stability of the device.

[0016] 3. The present utility model is provided with a guide rod, which guides the baffle, enabling the baffle to move stably, avoiding tilting during the movement of the baffle, and improving the guiding effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS
