High-drive bulldozer track auxiliary hanging chain tooling

Abstract

A track-mounted auxiliary chain attachment for a high-drive bulldozer is characterized by comprising an arc-shaped plate, with baffles connected to both sides of the arc-shaped plate via a fixed structure. Clamping bolts are installed on the outer side of the baffles, with the bolt shanks extending inward through the lower baffle of the arc-shaped plate. The clamping bolts are connected to the baffles via threaded connections, and are used to clamp the drive sprocket grooves on both sides, achieving radial fixation. A stop bar is installed on the side wall of the baffle between the arc-shaped plate and the clamping bolts. During use, the stop bar is inserted into the sprocket tooth groove, and when rotated, the sprocket teeth move the baffle, causing the attachment to rotate axially. Two baffles on the upper part of the arc-shaped plate have mounting holes on their side walls. Connecting bolts pass through the mounting holes of the two baffles and are threadedly connected to nuts. This allows for track movement without the need for other auxiliary vehicles or power sources, saving time and improving installation efficiency.

Description

Technical Field

[0001] This utility model relates to the field of track auxiliary chain technology, specifically to track auxiliary chain tooling for high-drive bulldozers. Background Technology

[0002] High-drive bulldozers are a special type of bulldozer design. Their main feature is that the drive sprocket is designed to be high up and far from the ground, which reduces the direct impact load on the drive sprocket that is in contact with the ground, thus significantly improving the life of the transmission system.

[0003] When installing tracks on existing high-drive bulldozers, the entire machine is first lifted off the ground using a hydraulic jack. An auxiliary vehicle then pulls the tracks with slings, causing the tracks to interlock and rewind between the guide wheel and the drive sprocket. This method requires other auxiliary vehicles to complete the track installation, which greatly limits the installation process. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an auxiliary track-mounting chain tooling for high-drive bulldozers, addressing the issue that requires other auxiliary vehicles to pull the tracks for installation. The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0005] A track-mounted auxiliary chain attachment for a high-drive bulldozer, characterized in that it includes:

[0006] Curved plate;

[0007] Two baffles are fixedly mounted on both sides of the arc-shaped plate.

[0008] The clamping bolts are located on the outside of the baffle. The shank of the clamping bolts extends inward through the baffle at the bottom of the arc-shaped plate. The clamping bolts are connected to the baffle by a threaded connection.

[0009] Mounting holes are provided on the side wall of the baffle at the upper part of the curved plate;

[0010] Connecting bolts and nuts; the connecting bolts pass through the mounting holes of the two baffles and are threaded into the nuts.

[0011] A stop bar is installed on the side wall of the baffle between the arc-shaped plate and the clamping bolt.

[0012] Furthermore, the clamping bolts are fitted with washers.

[0013] Furthermore, two clamping bolts are provided on the outer side of each baffle.

[0014] Furthermore, several mounting holes are spaced apart on the side wall of the baffle.

[0015] Furthermore, there are two stop levers, which pass through one side baffle and are connected to the other side baffle by threads.

[0016] The beneficial effects of this utility model are as follows: by setting this tooling, the track can be directly connected to the drive sprocket during installation, and then the drive sprocket can be started to drive the track to move. No other auxiliary vehicles or power sources are required to complete the movement of the track, saving time and improving installation efficiency. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the utility model will now be described in further detail with reference to the accompanying drawings and the following embodiments, so that the public can better understand the implementation method of this utility model. The specific implementation scheme of this utility model is as follows:

[0024] A track-assisted chain attachment for a high-drive bulldozer is characterized by comprising an arc-shaped plate 1, with baffles 2 fixedly connected to both sides of the arc-shaped plate 1. Clamping bolts 3 are installed on the outer side of the baffles 2, with the rods of the clamping bolts 3 extending inward through the lower part of the baffles 2 of the arc-shaped plate 1. The clamping bolts 3 are connected to the baffles 2 via threaded connections, and are used to clamp the drive sprocket grooves on both sides, achieving radial fixation. A stop bar 7 is installed on the side wall of the baffles 2 between the arc-shaped plate 1 and the clamping bolts 3. During use, the stop bar 7 is inserted into the sprocket tooth groove, and the sprocket rotates... The toothed baffle 7 drives the tooling to rotate axially; the two baffles 2 on the upper part of the arc plate 1 have mounting holes 4 on their side walls. The connecting bolts 5 pass through the mounting holes 4 of the two baffles 2 and are threaded to the nuts 6. The connecting bolts 5 can be directly connected to the pin holes of the track plates, or the sling hooks can be hung on the connecting bolts 5 to complete the track rewinding. By setting this tooling, the track can be directly installed on the drive sprocket during installation. Then, the drive sprocket is started to drive the track to move. The track can be moved without other auxiliary vehicles or power sources, saving time and improving installation efficiency.

[0025] It should be noted that the clamping bolt 3 is equipped with a washer 8.

[0026] To improve structural stability when connected to the sprocket, two clamping bolts 3 are provided on the outer side of each baffle 2, and there are two baffle rods 7. The baffle rods 7 pass through one baffle 2 and are connected to the other baffle 2 by threads, which facilitates disassembly and replacement of the baffle rods 7.

[0027] Several mounting holes 4 are spaced apart on the side wall of the baffle 2. In this embodiment, there are 5 holes, which facilitates connection with the track plate.

[0028] The working principle and process of this utility model are as follows:

[0029] The baffle 2 is fastened to both sides of the drive sprocket, and the lower end face of the arc plate 1 contacts the teeth of the sprocket. Then, the clamping bolt 3 is rotated so that the clamping bolt 3 extends into the groove of the sprocket and abuts against the side wall of the groove. At this time, the stop bar is inserted into the tooth groove of the sprocket. The connecting bolt 5 is passed through the lifting hole of the sling and connected to the nut 6. The other end of the sling is connected to one end of the track. Then, the drive sprocket is started to rotate, and the stop bar 7 is moved by the teeth of the sprocket, which in turn drives the tooling to rotate. The tooling drives the track to move through the sling, and the sling is wrapped around one side of the sprocket.

[0030] When the track is close to the sprocket, remove the lifting strap, remove the connecting bolt 5, pass the connecting bolt 5 through the pin hole of the track plate and connect it to the tooling, and then continue to rotate the sprocket until both ends of the track are on the right side of the sprocket. Use the pin to connect the two ends to complete the installation of the track.
