Description

Technical Field

[0001] The utility model relates to the technical field of shovel loaders, in particular to a shovel loader counterweight beam with a buffer function. Background Art

[0002] Shovel loaders are generally used for loading and unloading bulk materials such as sand and gravel. They are commonly used industrial vehicles in manufacturing and construction industries. They have the characteristics of strong loading capacity, high operating efficiency and wide range of applications. They are widely used in construction, manufacturing, mining, ports and other fields. The counterweight behind the shovel loader refers to some weight hung on the rear end of the frame or the end of the lifting arm to increase the weight of the shovel loader itself and thus improve its stability.

[0003] In the prior art, a shovel loader generally has a counterweight beam installed at the edge of the frame, and a counterweight suitable for the vehicle is placed inside the beam. Common counterweights include iron blocks, concrete blocks, etc., which are placed at the rear end of the frame through the beam structure. When applied to the rear end of a shovel loader, the counterweight beam generally plays a role of counterweight and rear end protection, but the traditional counterweight beam has an effective protective effect. When a collision occurs, the beam body itself has insufficient buffering, and the counterweight carried inside it is prone to shaking or unstable placement, thereby affecting the overall stability of the shovel loader and posing a safety hazard. Utility Model Content

[0004] Therefore, the purpose of the utility model is to provide a shovel loader counterweight beam with a buffering function to solve the problems raised in the above background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a shovel loader counterweight beam with a buffering function, comprising a main body, a buffer frame is connected to the outside of the main body, and a counterweight bin is embedded in the inside of the main body;

[0006] The buffer frame includes an outer frame plate, the outer wall of the outer frame plate is attached with an energy absorption frame, the middle part of the inner wall of the outer frame plate is connected with a spring pile, and linkage rods are distributed on both sides of the spring pile. One end of the linkage rod is hinged on the inner wall of the outer frame plate, and the other end is hinged with a slider, and the slider is slidably arranged in a slide groove opened on the rear wall of the main body.

[0007] Furthermore, a soft rubber head is connected to one end of the slider away from the linkage rod, a force-bearing seat is provided at the outer end of the slide slot, the force-bearing seat is integrally formed with the main body, and the force-bearing seat is connected to the outer frame plate by bolts.

[0008] Furthermore, the two linkage rods are symmetrically distributed on both sides of the spring pile.

[0009] Furthermore, the main body includes a main frame, both ends of the main frame are connected with buckle frames, the outer wall of the buckle frame is provided with a groove, bolt rods are distributed on both sides of the groove, and the bottom end of the main frame is connected to the mounting frame.

[0010] Furthermore, the main frame is slidably matched with the outer frame plate through grooves at both ends.

[0011] Furthermore, the counterweight bin includes a bin body, and the bin body is opened inside the main body, a counterweight groove is opened inside the bin body, and a counterweight block is clamped inside the counterweight groove.

[0012] Furthermore, the counterweight grooves are opened at equal intervals along the interior of the warehouse body.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The counterweight beam of the shovel loader is used in combination with a main body and a buffer frame. When it is impacted or bumped, it can first be buffered and absorbed through the outer frame plate and the energy absorption frame of the outermost hollow shell structure. Then the outer frame plate body beam is impacted and the force is transferred to the spring pile for buffering. At the same time, the two ends of the outer frame plate shrink and slide along the groove; the outer frame plate drives the linkage rod to swing, and then drives the slider to slide toward the two ends until the soft rubber head at the end of the slider contacts the force seat to complete the buffering process, thereby achieving gradual buffering under the stress state and reducing the impact on the counterweight structure itself and the frame.

[0015] 2. The counterweight beam of the shovel loader is mounted on the rear end of the shovel loader frame through the clips at both ends of the main frame, and is reinforced with bolts distributed at both ends; it is welded and fixed to the main frame through the bottom mounting frame and the clips at both ends to keep the structure stable after the counterweight beam is installed.

[0016] 3. The counterweight beam of the shovel loader has a bin inside the main frame for counterweighting, and the bin accommodates counterweight blocks of appropriate specifications through counterweight slots opened at equal intervals. Counterweight blocks of different materials or quantities can be adjusted and replaced according to usage requirements, which is convenient and flexible to use. BRIEF DESCRIPTION OF THE DRAWINGS

Bolt rods 104 are distributed on both sides of the groove 103 . The bottom end of the main frame 101 is connected to a mounting frame 105 .

[0027] In order to maintain the stability of the shovel loader counterweight beam structure, Figure 1 As shown, the counterweight beam of the shovel loader is mounted on the rear end of the shovel loader frame through the clip frames 102 at both ends of the main frame 101, and is reinforced and connected to the frame through the bolt rods 104 distributed at both ends; the bottom mounting frame 105 and the clip frames 102 at both ends are fixed to the main frame 101 by welding to keep the structure stable after the counterweight beam is installed.

[0028] like Figure 2 , 3As shown, the buffer frame 2 is connected to the rear part of the main body 1, including an outer frame plate 201, and the outer wall of the outer frame plate 201 is fitted with an energy absorption frame 202; a spring pile 203 is installed in the middle of the inner wall of the outer frame plate 201; linkage rods 204 are distributed on both sides of the spring pile 203, and the linkage rods 204 are symmetrically distributed on both sides of the spring pile 203, one end of the linkage rod 204 is hinged on the inner wall of the outer frame plate 201, and the other end is hinged with a slider 205, and the end of the slider 205 away from the linkage rod 204 is connected with a soft rubber head 206, and the slider 205 is slidably arranged in a slide groove 207 opened on the rear wall of the main body 1 (specifically the main frame 101); a force seat 208 is provided at the outer end of the slide groove 207, the force seat 208 is integrally formed with the main frame 101, and the force seat 208 is bolted to the outer frame plate 201.

[0029] In order to achieve good buffering performance when the shovel loader is in use, this buffer frame 2 is used in combination with the outer frame plate 201 and the main frame 101. When impacted or knocked, the energy absorption frame 202 with an outermost hollow shell structure can be used for buffering first; then the outer frame plate 201 body is impacted, and the force is transferred to the spring pile 203 for buffering; at the same time, the two ends of the outer frame plate 201 are telescopically slid with the grooves 103 on the buckle frame 102 as the guide; at the same time, the linkage rod 204 drives the slider 205 to slide toward the two ends under force until the soft rubber head 206 at the end of the slider 205 contacts the force seat 208 to complete the buffering process, thereby achieving gradual buffering under force, reducing the impact on the counterweight structure itself and the frame, and improving safety.

[0030] like Figure 4 As shown, the counterweight bin 3 is used to place the counterweight, and includes a bin body 301, and the bin body 301 is opened inside the main frame 101, a counterweight slot 302 is opened inside the bin body 301, and a counterweight block 303 is placed inside the counterweight slot 302.

[0032] In summary, when the shovel loader counterweight beam is in use, the main frame 101 can be installed by engaging the buckle frames 102 at both ends with the rear end of the shovel loader frame, and the bottom mounting frame 105 and the buckle frames 102 at both ends are fixed to the main frame 101 by welding, and the bolt rods 104 distributed at both ends are used to reinforce the connection with the frame; after the installation is completed, the counterweight is adjusted according to the actual use requirements, and the corresponding counterweight block 303 is engaged and placed in the counterweight groove 302. After the assembly is completed, when it is hit, the outer frame plate 201 and the energy absorption frame 202 can be subjected to force for the first buffering, and the outer frame plate 201 and the energy absorption frame 202 slide along the groove 103 during the buffering; the force after the first buffering is transmitted to the spring pile 203 and the linkage rod 204 for the second buffering, and then the slider 205 slides along the slide groove 207 during the buffering, and the slider 205 at both ends slides and contacts the force bearing seat 208 for the third buffering, reducing the impact of the front force and completing the buffering process.

[0033] The above description is only an illustration of some preferred embodiments and the technical principles used. Those skilled in the art should understand that the technical solution of the utility model is not limited thereto, and any combination or equivalent replacement of the above technical features or their equivalent features without departing from the concept of the present invention should be within the protection scope of the utility model.
