Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, and in particular to a rapid tunneling device for an integrated tunneling and anchoring machine. Background Technology

[0002] A coal mine is an area where humans extract coal resources in coal-rich areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, tunnels are typically dug underground to extract the coal; this is called an underground coal mine.

[0003] A roadheader-anchor machine is used to excavate coal mine tunnels underground. The roadheader-anchor machine has a bucket at the bottom of its forward end, with a rotating pusher arm on the bucket to remove the excavated coal. Typically, the pusher arm is connected to the bucket as a whole; if it becomes damaged after a period of time, the entire arm needs to be replaced, which is heavy and cumbersome.

[0004] In view of this, we propose a rapid tunneling device for an integrated tunneling and anchoring machine. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a rapid tunneling device for an integrated tunneling and anchoring machine, so as to solve the technical problem that the current pusher arm needs to be replaced as a whole when it is damaged, which is relatively heavy and troublesome.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: design a rapid tunneling device for an integrated tunneling and anchoring machine, including an integrated tunneling and anchoring machine body, and also including a bucket and a ore pushing structure;

[0007] The bucket is positioned at the bottom of the forward end of the integrated excavator and anchor machine body;

[0008] Two ore-pushing structures are symmetrically arranged on the bucket;

[0009] The pushing structure includes a connecting plate, a mounting plate, a collar, and a pushing arm;

[0010] The connecting disc is rotatably mounted on the top side of the bucket;

[0011] The mounting plate is fixed to the top side of the connecting plate;

[0012] The collar is fitted onto the mounting plate;

[0013] The collar is fixedly connected to the mounting plate by a plurality of bolts arranged in a ring array; the bolts pass through holes opened in the collar, and the inner end of the bolts is connected to threaded holes opened in the outer ring wall of the mounting plate;

[0014] Several pusher arms are fixed in a ring array on the outer wall of the collar.

[0015] Preferably, the outer ring wall of the mounting plate is fixed with a plurality of insert blocks in a ring array, and the inner ring wall of the collar is provided with a plurality of slots in a ring array, wherein the insert blocks are inserted into and cooperate with the slots;

[0016] The insertion block and slot are offset from the bolt installation position.

[0017] Preferably, the insertion end of the plug has beveled surfaces on both sides, and the insertion end of the plug has a trapezoidal structure design.

[0018] Preferably, an extension arm is fixedly provided on the top side of several of the pushing arms;

[0019] Both the pusher arm and the extension arm are designed with a chamfered structure.

[0020] Preferably, the outer end of the pusher arm is provided with a protruding hook;

[0021] The protruding hook is hook-shaped at the outer end of the pusher arm.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. This utility model, by setting up a connecting plate, mounting plate, collar, bolts and pusher arm, has the advantage that when disassembling, the pusher arm and collar can be directly disassembled together, while the connecting plate and mounting plate remain unchanged, allowing for partial replacement.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0036] Example 1: A rapid tunneling device for an integrated tunneling and anchoring machine, see [link / reference] Figures 1 to 5 It includes the body 1 of the integrated tunneling and anchoring machine, as well as the bucket 2 and the ore pushing structure 3; the bucket 2 is arranged at the bottom of the forward end of the integrated tunneling and anchoring machine body 1; the two ore pushing structures 3 are symmetrically arranged on the bucket 2;

[0037] The pushing structure 3 includes a connecting plate 301, a mounting plate 302, a collar 303, and pushing arms 305. The connecting plate 301 is rotatably mounted on the top side of the bucket 2. The mounting plate 302 is fixedly mounted on the top side of the connecting plate 301. The collar 303 is sleeved on the mounting plate 302. The collar 303 is fixedly connected to the mounting plate 302 by a number of bolts 304 arranged in a ring array. The bolts 304 pass through holes opened in the collar 303, and the inner end of the bolts 304 is connected to the threaded hole opened in the outer ring wall of the mounting plate 302. A number of pushing arms 305 are fixedly mounted in a ring array on the outer ring wall of the collar 303.

[0038] This utility model, by setting up a connecting plate 301, a mounting plate 302, a collar 303, bolts 304, and a pusher arm 305, has the advantage that during disassembly, the pusher arm 305 can be directly disassembled together with the collar 303, while the connecting plate 301 and the mounting plate 302 remain unchanged, allowing for partial replacement. This solves the problem that when the pusher arm is damaged, it needs to be replaced as a whole, which is heavy and troublesome.

[0039] Specifically, the outer ring wall of the mounting plate 302 is fixed with a number of inserts 3021 in a ring array, and the inner ring wall of the collar 303 is provided with a number of slots 3031 in a ring array. The inserts 3021 are inserted and engaged with the slots 3031; wherein the positions of the inserts 3021 and the slots 3031 are staggered from those of the bolts 304.

[0040] This utility model, by setting the insert block 3021 and the slot 3031, has the advantage that when installing the collar 303, the collar 303 is accurately connected to the mounting plate 302 through the docking of the insert block 3021 and the slot 3031, and the hole opened on the collar 303 accurately corresponds to the threaded hole opened on the outer ring wall of the mounting plate 302.

[0041] Furthermore, the insertion end of the insert 3021 is provided with beveled surfaces 3022 on both sides, and the insertion end of the insert 3021 has a trapezoidal structure design. The narrow insertion end of the insert 3021 facilitates insertion into the slot 3031.

[0042] Furthermore, several pusher arms 305 are fixedly provided with extension arms 306 on their top sides; both the pusher arms 305 and the extension arms 306 are designed with a beveled structure. The extension arms 306 are provided to increase the height of the pusher, and the beveled design distributes the force during the push.

[0043] It is worth noting that the outer end of the pusher arm 305 is provided with a protruding hook 3051; wherein, the protruding hook 3051 is hook-shaped with the outer end of the pusher arm 305. The protruding hook 3051 helps to hook and push the material.

[0044] Working principle: Using the device of this utility model, the pusher arm 305 is installed, the collar 303 is placed on the mounting plate 302, and the narrow insertion end of the insert block 3021 is inserted into the slot 3031 until the collar 303 is completely fitted onto the mounting plate 302. The hole on the collar 303 corresponds precisely to the threaded hole on the outer ring wall of the mounting plate 302. The bolt 304 passes through the hole on the collar 303, and the inner end of the bolt 304 connects with the threaded hole on the outer ring wall of the mounting plate 302, fixing the collar 303, thereby fixing the pusher arm 305. During the tunneling process, the rotating pusher arm 305 pushes the ore on the bucket 2 into the tunneling and anchoring machine body 1. When disassembling and replacing the pusher arm 305, loosen and remove the bolt 304, and remove the collar 303 and the pusher arm 305 for replacement.

[0045] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
