Description

Technical Field

[0001] The utility model relates to the technical field of excavators, and specifically relates to a rapid assembly of an excavator frame. Background Technique

[0002] An excavator, also known as an excavation machine or a power shovel, is an earthmoving machine that uses a bucket to excavate materials above or below the machine surface and loads them into transport vehicles or unloads them onto a stockpile yard. In the prior art, when assembling the frame, processing personnel use the methods of positioning, welding, and screwing the frame. This method requires frequent operations by the staff and cannot be quickly assembled, resulting in low work efficiency.

[0003] For example, the patent application number is CN202322879072.5. This utility model discloses a lightweight upper frame of an excavator that is easy to assemble, which affects the connection stability between the vertical frame and the bottom frame. The tail end of the fixing bolt is located in the receiving groove to avoid bumping with the outside world and causing rotation, thus affecting the connection stability between the vertical frame and the bottom frame. The assembly of the upper frame of the excavator is convenient and does not affect stability. In use, processing personnel use the methods of positioning, welding, and screwing the frame. This method requires frequent operations by the staff and cannot be quickly assembled, resulting in low work efficiency.

[0004] For example, the patent application number is CN201320318995.7. This utility model discloses an excavator frame. The structure of this utility model is reasonable and the design is novel. Since the gas tank is installed in the counterweight at the rear of the frame, the space inside the counterweight is fully utilized, and there is no need to place the gas tank outside, avoiding collisions and having high safety and stable center of gravity. Moreover, the gas tank mounting seat can mount two gas tanks, greatly improving the endurance of the excavator. This utility model solves the technical problems of poor safety, unstable center of gravity, easy aging, and low endurance in the prior art. In use, processing personnel use the methods of positioning, welding, and screwing the frame. This method requires frequent operations by the staff and cannot be quickly assembled, resulting in low work efficiency. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 - 3 and 5, the present invention provides a technical solution: a rapid assembly of an excavator frame, including a frame main board 1, installation mechanisms 2 are arranged on both sides of the frame main board 1, and side plates 3 are arranged on the sides of the installation mechanisms 2 close to the frame main board 1.

[0026] The installation mechanism 2 includes an installation plate 201. On one side of the installation plate 201 close to the side plate 3, there is a card slot 202. Inside the card slot 202, there is a card board 203. The cross-sectional shapes of both the card board 203 and the card slot 202 are T-shaped. At one end of the card slot 202, there is a groove 204, and the connection between the groove 204 and the card slot 202 is communicated. Inside the groove 204, there is a moving plate 205. At one end of the moving plate 205, there is a fixing plate 206. At the end of the fixing plate 206 away from the moving plate 205, there is a cross plate 207. The moving plate 205 is fixedly connected to the cross plate 207 through the fixing plate 206. On the back of the fixing plate 206, there is a limiting rod 208 fixedly arranged. At the other end of the moving plate 205, there is a connecting spring 209. At one end of the card board 203, there is a baffle 210.

[0027] One end of the card board 203 is fixedly connected to the side plate 3, and when the card board 203 contacts the installation plate 201, the card board 203 can enter into the card slot 202 and contact with the installation plate 201. On the side of the moving plate 205 away from the baffle 210, there is a sleeve 211. At one end of the sleeve 211, there is a round rod 212, and the round rod 212 is movably connected to the sleeve 211. Through the movement of the round rod 212, one end of the round rod 212 can enter into the sleeve 211 and compress the connecting spring 209 outside the round rod 212.

[0028] Please refer to Figure 1 and 4 The connecting spring 209 is arranged around the outside of the round rod 212 and the sleeve 211. On the surface of one end of the card board 203, there is a slot 213, and the slot 213 is adapted to the limiting rod 208. On one side of the baffle 210, there is an adjusting rod 214. One end of the adjusting rod 214 extends to the outside of the installation plate 201. When the limiting rod 208 moves, it will enter into the slot 213, improving the stability of the card board 203.

[0029] Between the baffle 210 and the moving plate 205, there is a compression spring 215. The adjusting rod 214 is movably connected to the moving plate 205, and the adjusting rod 214 penetrates through the moving plate 205. When the adjusting rod 214 moves, the moving plate 205 will not move due to the movement of the adjusting rod 214. On one side of the compression spring 215, there is a resisting rod 216, and the length of the resisting rod 216 is less than the length of the connecting spring 209. Both the baffle 210 and the moving plate 205 contact with the card board 203.

[0030] During operation, first move the adjusting rod 214. Since the adjusting rod 214 is movably connected to the moving plate 205 and the mounting plate 201 respectively, the movement of the adjusting rod 214 is ensured. And through the movement of the adjusting rod 214, the baffle 210 can be moved, so that the distance between the baffle 210 and the moving plate 205 is reduced, and the compression spring 215 is compressed, causing the compression spring 215 to deform and the abutting rod 216 to move simultaneously, improving the work efficiency. During the movement of the abutting rod 216, the abutting rod 216 can be brought into contact with the moving plate 205. Through the continuous movement of the baffle 210, at this time the abutting rod 216 has been in contact with the moving plate 205, which will cause the moving plate 205 to move simultaneously, so that the moving plate 205 and the baffle 210 gradually enter into the groove 204. When the moving plate 205 moves, the connecting spring 209 can be deformed, causing the connecting spring 209 to be compressed, and at the same time, it will also push the round rod 212 and the fixing plate 206 to move. When the round rod 212 moves, since the round rod 212 is movably connected to the sleeve 211, one end of the round rod 212 can enter into the sleeve 211. When the fixing plate 206 moves, it pushes the cross plate 207 and the limiting rod 208 to move simultaneously, so that both the baffle 210 and the limiting rod 208 can enter into the groove 204, facilitating subsequent operations. Then, the clamping plate 203 is combined with the clamping groove 202 on the surface of the mounting plate 201. Since the clamping groove 202 is adapted to the clamping plate 203, and the cross-sectional shapes of the clamping plate 203 and the clamping groove 202 are both T-shaped, it can prevent left-right detachment after combination. And after the clamping plate 203 and the clamping groove 202 are combined, through the reset function of the compression spring 215 and the connecting spring 209, the baffle 210 can be located at one end of the clamping plate 203 to block the clamping plate 203, and the movement of the limiting rod 208 will enter into the internal cavity 213 to block again, thereby reducing manual operations and quickly carrying out the assembly work, improving the work efficiency.
