Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering machinery technology, and in particular to an anti-collision installation structure for a reversing camera on an excavator balance weight. Background Technology
[0002] Currently, the reversing camera structure of excavator counterweights typically has holes centered on both sides of the counterweight. A round tube connects the two ends inside, serving as a wiring conduit. Threaded mounts are pre-embedded on both sides of the wiring conduit on the rear of the counterweight. The camera is mounted on the threaded mount at the rear end of the wiring conduit, protruding from the rear surface. This structure causes the rear-view camera to protrude from the rear frame of the counterweight, lacking protection and making it susceptible to damage during machine movement. Furthermore, the fixed mounting surface of the reversing camera prevents adjustment of the shooting angle, leading to increased maintenance costs, a poor appearance, and reduced customer satisfaction. Utility Model Content
[0003] The purpose of this utility model is to provide an anti-collision installation structure for excavator balance iron reversing camera to solve the problems mentioned in the background art.
[0004] A counterweight reversing camera anti-collision mounting structure for excavators includes a counterweight. The counterweight has a receiving cavity on its rear end face, a groove module is fixedly connected within the receiving cavity, and a mounting structure is fixedly connected to the groove module. The mounting structure has a welding nut, and a camera is detachably connected to the mounting structure via the welding nut.
[0005] Preferably, the mounting structure includes a mounting plate, which is inclined, and a connecting plate is provided at the bottom end of the mounting plate. A fixing plate is fixedly connected to the bottom end of the connecting plate and the top end of the mounting plate, and the connection between the mounting plate and the connecting plate is inclined toward the interior of the receiving cavity.
[0006] Furthermore, the mounting structure is characterized by being formed by bending a sheet material.
[0007] Preferably, the receiving cavity is located at the upper part of the center of the rear end face of the balance iron, and a wire tube is also provided inside the balance iron. One end of the wire tube is connected to the receiving cavity, and the other end of the wire tube passes through the balance iron.
[0008] Furthermore, the mounting plate has mounting holes, and a camera is installed in the mounting holes, with the camera completely located within the receiving cavity.
[0009] Compared with the prior art, the advantages of this utility model are as follows: A receiving cavity is opened at the rear of the balance iron, and a groove module is fixedly connected inside the receiving cavity. An installation structure is fixedly connected at the opening end of the groove module that overlaps with the receiving cavity. The installation structure is a bent plate, which includes an inclined mounting plate. The lower end of the mounting plate is inclined away from the rear of the balance iron, thus reserving a recessed space within the receiving cavity. This allows the camera to be completely placed inside the receiving cavity when fixedly connected to the mounting plate, without protruding from the balance iron. Therefore, during normal operation of the excavator, when it is bumped or rubbed, the balance iron will contact the camera, preventing damage. The top of the mounting plate on the bottom of the mounting plate is fixedly connected to the receiving cavity through two overlapping fixing plates, forming a cavity structure that protects the camera. A conduit is also installed inside the balance iron to pass the camera's wiring through the balance iron, preventing damage from bumps and friction that could affect the camera's operation.

[0014] The following will describe specific embodiments and appendices. Figure 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.
[0015] A counterweight reversing camera anti-collision installation structure 4 for excavators includes a counterweight 1, which is a commonly used tool placed at the rear end of an excavator to balance the center of gravity of the excavator. The counterweight 1 can be hollow and then counterweighted by quantitatively pouring concrete or other materials, or it can be a solid structure cast in one piece of metal. A receiving cavity 2 is opened on the rear end face of the counterweight 1. The receiving cavity 2 is located at the upper part of the center of the rear end face of the counterweight 1. Located in the upper middle part, the camera 6 can capture the image completely and has a good field of view.
[0016] A groove module 3 is fixedly connected inside the receiving cavity 2. The groove module 3 is a cubic structure with one open side. The groove module 3 is placed inside the receiving cavity 2 and fits tightly with the receiving cavity 2. The open side of the groove module 3 faces the opening of the receiving cavity 2 of the balance iron 1. An installation structure 4 is fixedly connected to the groove module 3. The installation structure 4 is fixedly connected to both the groove module 3 and the balance iron 1.
[0017] The mounting structure 4 includes a mounting plate 4241, which is inclined. The left and right sides of the mounting plate 4241 are fixedly connected to the groove module 3 by welding, completely sealing the groove module 3 and preventing dust generated during construction from entering the groove module 3 and affecting its operation. A connecting plate is provided at the bottom of the mounting plate 4241. The connection between the mounting plate 4241 and the connecting plate is inclined towards the inside of the receiving cavity 2. The angle between the connecting plate and the mounting plate 4241 is greater than or equal to 90 degrees. A fixing plate 43 is fixedly connected to the bottom of the connecting plate and the top of the mounting plate 4241. The planes of the two fixing plates 43 are the same plane, which is used to fix the mounting structure 4 to the balance iron 1. The entire mounting structure 4 is formed by bending sheet metal, which is simple and convenient.
[0018] Mounting plate 4241 has mounting holes for the camera 6 to pass through. Welding nuts 5 are welded to the inner side of mounting plate 4241. The camera 6 module can be fixed to mounting plate 4241 by bolts and threaded connection of welding nuts 5. A rubber ring is provided between the two for dust prevention. The camera 6 and the rubber ring are existing technologies. After the camera 6 is installed, because the mounting plate 4241 is tilted, the part of the camera 6 that passes through the mounting hole is still completely located in the receiving cavity 2. When the balance iron 1 is damaged or scratched by walls, trees, etc., the balance iron 1 can contact the obstacle, which can prevent the camera 6 from being damaged and ensure the durability of the reversing image.
[0019] The balance iron 1 is also equipped with a conduit that runs through the balance iron 1 and is connected to the receiving cavity 2. It can be used for wiring so that the camera 6 can transmit signals and be powered.
[0020] Except for the technical features described in the specification, all other technologies are known to those skilled in the art.
[0021] In this utility model, "upper", "lower", "left", "right", "front" and "back" are relative positions used to facilitate the description of positional relationships, and therefore cannot be understood as absolute positions as a limitation on the scope of protection.
[0022] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
