Technical Field

[0001] This utility model relates to the field of maintenance and debugging tooling technology, and in particular to a maintenance and debugging load-bearing weight. Background Technology

[0002] The maintenance cranes and cantilever cranes for the aforementioned bridge project need to be installed and commissioned at the manufacturing base. Different users and different project models have different requirements. Currently, when commissioning maintenance cranes, slings or wire ropes are often used to pass through the bottom to hold the counterweight before lifting. Furthermore, wave ropes are used to hold the crane during the lifting process. This method is not only unsuitable for different counterweight requirements, but also inefficient, unstable, and unsafe. In addition, the right-angled edges of the counterweights can easily damage the slings or wire ropes, failing to meet quality, safety, and environmental protection requirements.

[0003] Therefore, this utility model proposes a maintenance and adjustment load-bearing weight to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a load-bearing weight for maintenance and adjustment of a crane, which can meet different counterweight requirements and improve the safety of use.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a maintenance crane adjustment load weight, the innovation of which is: including a test weight frame and a counterweight unit composed of several superimposed counterweight blocks; The test weight frame includes a frame body and four first lifting lugs. The frame body includes an upper frame, a lower frame, and intermediate columns. The lower frame has a counterweight unit support surface in the middle of its top surface. There are four intermediate columns arranged in a U-shape around the counterweight unit support surface. The bottom ends of the four intermediate columns are fixedly connected to the lower frame. The upper frame is set above the lower frame and located between the four intermediate columns. The side walls of the upper frame are fixedly connected to the side walls of the four intermediate columns. The upper frame has a first opening in the middle for taking out and placing the counterweight unit. The four first lifting lugs correspond one-to-one with the four columns. The first lifting lugs are set above the upper frame. One side of the first lifting lug is fixedly connected to the top surface of the upper frame, and the other side is fixedly connected to the side wall of the corresponding column.

[0006] Furthermore, the frame body has a second opening between two adjacent intermediate columns for horizontally removing the counterweight, and a detachable door frame is provided at the second opening.

[0007] Furthermore, the detachable door frame includes an upper horizontal beam and a longitudinal beam. The upper horizontal beam is connected above the longitudinal beam and cooperates with the longitudinal beam to form a T-shaped structure. Each end of the upper horizontal beam is horizontally connected to a hanging rod, and each hanging rod is set outside the first lifting lug on the same side. The upper frame has a first limiting groove for each hanging rod to enter from top to bottom, and the hanging rod is set in the corresponding first limiting groove. The lower frame has a second limiting groove for the longitudinal beam to be inserted from top to bottom, and the bottom of the longitudinal beam is inserted into the second limiting groove.

[0008] Furthermore, the central axis of the hanging rod is perpendicular to the central axis of the lifting hole of the first lifting lug on the same side. The first lifting lug is equipped with a maintenance crane hook, which is movably inserted into the lifting hole of the first lifting lug. The maintenance crane hook covers the opening of the first limiting groove, thus limiting the hanging rod within the first limiting groove.

[0009] Furthermore, the test weight frame also includes several limiting plates, which are distributed around the edges of the counterweight unit support surface and cooperate with the counterweight unit support surface of the lower frame to form a counterweight unit limiting groove. Each limiting plate is vertically connected to the inner wall of the frame body or the detachable door frame at the corresponding position.

[0010] Furthermore, the top of the limiting plate is bent to form a guide plate, which is inclined from top to bottom toward the support surface of the counterweight unit.

[0011] Furthermore, a vertically arranged reinforcing plate is provided on the side of the limiting plate away from the counterweight unit limiting groove, and the top of the reinforcing plate extends to the guide plate. The reinforcing plate is vertically fixedly connected to both the limiting plate and the guide plate.

[0012] Furthermore, the lower frame has several horizontally arranged forklift slots.

[0013] The advantages of this utility model are: (1) The load-bearing weight of this utility model consists of a test weight frame and a counterweight unit. The counterweight unit is placed inside the test weight frame. The counterweight unit is composed of several counterweight blocks that are stacked on each other. Before use, the weight can be placed on the weighing tool. Different load-bearing requirements can be met by placing different numbers of counterweight blocks inside the test weight frame. After the load-bearing adjustment is completed, the maintenance crane can directly connect to the first lifting lug to lift the test weight frame containing the counterweight unit for debugging. The operation is convenient and the safety is higher.

[0014] (2) The frame body of this utility model has a second opening between two adjacent middle columns for horizontally removing the counterweight. The second opening is provided with a detachable door frame, which makes it convenient to remove the corresponding counterweight by horizontally pulling each counterweight of the counterweight unit to complete the counterweight adjustment.

[0015] (3) The detachable door frame of this utility model adopts a T-shaped structure, and the upper and lower parts are detachably connected to the frame body by plugging, making installation and disassembly convenient.

[0016] (4) This utility model utilizes the hook of the maintenance crane used for lifting weights. By optimizing the relative position of the hanging rod and the first lifting lug, when the maintenance crane is being adjusted, after the hook of the maintenance crane is inserted into the lifting hole of the first lifting lug, the hanging rod is automatically limited in the first limiting groove and locked. This prevents the detachable door frame from accidentally falling off the test weight frame during the adjustment of lifting and lowering the weight. After the weight is placed on the ground after the adjustment is completed, the hook of the maintenance crane can be removed to unlock it. The operation is convenient.

[0017] (5) This utility model utilizes several limiting plates to cooperate with the counterweight unit support surface of the lower frame to form a counterweight unit limiting groove, thereby limiting the position of the counterweight unit in the test weight frame, preventing the counterweight unit from moving, and ensuring the stability of the center of gravity of the weight.

[0018] (6) This utility model forms a guide plate by bending the top of the limiting plate, which guides the counterweight unit when the entire assembly is hoisted and lowered into the test weight frame.

[0019] (7) By setting a reinforcing plate on the outside of the limiting plate and extending the top of the reinforcing plate to the guide plate, the present invention simultaneously strengthens the limiting plate and the guide plate, effectively improving the structural strength of the limiting plate and the guide plate and preventing deformation of the limiting plate and the guide plate.

[0020] (8) The lower frame of this utility model is provided with a forklift slot, which allows the fork of a forklift to be inserted, making it convenient for construction workers to lift and move the weight using a forklift. Attached Figure Description

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] Example This embodiment provides a load-bearing weight for maintenance and debugging of a crane, such as... Figure 1-3 As shown, it includes a test weight frame 1 and a counterweight unit 2 composed of several stacked counterweight blocks 21. Each counterweight block 21 has two second lifting lugs 22 on each side in the width direction to facilitate the lifting and stacking of the counterweight blocks.

[0027] The test weight frame 1 includes a frame body and four first lifting lugs 14. The frame body includes an upper frame 13, a lower frame 11, and intermediate columns 12. The upper frame 13, lower frame 11, and intermediate columns 12 are all assembled from I-beams. The lower frame 11 has a counterweight unit 2 support surface in the middle of its top surface. There are four intermediate columns 12 arranged in a U-shape around the support surface of the counterweight unit 2. The bottom ends of the four intermediate columns 12 are welded and fixedly connected to the lower frame 11. The upper frame 13 is located above the lower frame 11 and between the four intermediate columns 12. The side walls of the upper frame 13 are welded and fixedly connected to the side walls of the four intermediate columns 12. The upper frame 13 has a first opening in the middle for taking out and placing the counterweight unit 2. The four first lifting lugs 14 correspond one-to-one with the four columns. The first lifting lugs 14 are located above the upper frame 13. One side of the first lifting lug 14 is welded and fixedly connected to the top surface of the upper frame 13, and the other side is welded and fixedly connected to the side wall of the corresponding column.

[0028] In this embodiment, there is a second opening between two adjacent middle columns 12 on the frame body for horizontally removing the counterweight 21. There are two second openings, located on both sides of the width direction of the frame body. Each second opening is provided with a detachable door frame 15, which facilitates the horizontal pulling of each counterweight 21 of the counterweight unit 2 to remove the corresponding counterweight 21 to complete the counterweight adjustment. It is not necessary to lift the counterweight 21 from the first opening above one by one, making the counterweight adjustment more convenient.

[0029] In this embodiment, the detachable door frame 15 includes an upper horizontal beam 151 and a longitudinal beam 152. The upper horizontal beam 151 is welded to the upper part of the longitudinal beam 152 and forms a T-shaped structure with the longitudinal beam 152. A hanging rod 153 is horizontally welded to each end of the upper horizontal beam 151. Each hanging rod 153 is located outside the first lifting lug 14 on the same side. The upper frame 13 has a first limiting groove 131 for each hanging rod 153 to enter from top to bottom. The hanging rod 153 is located in the corresponding first limiting groove 131. A plug plate 154 is vertically welded to the bottom of the longitudinal beam 152. The lower frame 11 has a second limiting groove 112 for the plug plate 154 of the longitudinal beam 152 to be inserted from top to bottom. The plug plate 154 at the bottom of the longitudinal beam 152 is inserted into the second limiting groove 112. The detachable door frame 15 is easy to install and disassemble.

[0030] In this embodiment, the central axis of the hanging rod 153 is perpendicular to the central axis of the lifting hole of the first lifting lug 14 on the same side. The first lifting lug 14 is equipped with a maintenance crane hook. When the maintenance crane is being adjusted, the maintenance crane hook moves through the lifting hole of the first lifting lug 14 and covers the opening of the first limiting groove 131, thus limiting the hanging rod 153 within the first limiting groove 131 and locking it in place. This prevents the detachable door frame 15 from accidentally detaching from the test weight frame 1 and falling during the adjustment of the weight lifting and lowering process. After the weight is dropped after the adjustment is completed, the maintenance crane hook can be removed to unlock the crane, making the operation convenient.

[0031] In this embodiment, the test weight frame 1 also includes six limiting plates 16. These six limiting plates 16 are distributed around the perimeter of the supporting surface of the counterweight unit 2, and cooperate with the supporting surface of the counterweight unit 2 of the lower frame 11 to form a limiting groove for the counterweight unit 2. This limits the position of the counterweight unit 2 within the test weight frame 1, preventing movement and ensuring the stability of the weight's center of gravity. Two of the six limiting plates 16 are respectively located on both sides of the length of the frame body, and the remaining four limiting plates 16 are arranged in two groups of two, respectively on the detachable door frames 15 at the two second openings. Each limiting plate 16 is vertically welded to the inner wall of the corresponding frame body or detachable door frame 15. The top of each limiting plate 16 is bent to form a guide plate 161. The guide plate 161 tilts downwards towards the supporting surface of the counterweight unit 2, guiding the counterweight unit 2 when it is hoisted and lowered into the test weight frame 1. Each limiting plate 16 has a vertically arranged reinforcing plate 17 on the side away from the limiting groove of the counterweight unit 2. The top of the reinforcing plate 17 extends to the guide plate 161. The reinforcing plate 17 is vertically welded and fixedly connected to the limiting plate 16 and the guide plate 161, which effectively improves the structural strength of the limiting plate 16 and the guide plate 161 and prevents the limiting plate 16 and the guide plate 161 from deforming.

[0032] In this embodiment, the lower frame 11 has several horizontally arranged forklift slots 111 for forklift forks to be inserted, making it convenient for construction workers to lift and move weights using forklifts.

[0033] The load-bearing weight consists of a test weight frame 1 and a counterweight unit 2. The counterweight unit 2 is placed inside the test weight frame 1 and is composed of several superimposed counterweight blocks 21. Before use, the weight can be placed on the weighing tool. By placing different numbers of counterweight blocks 21 inside the test weight frame 1, different load-bearing requirements can be met. After the load-bearing adjustment is completed, the maintenance crane directly connects to the first lifting lug 14 to lift the test weight frame 1 containing the counterweight unit 2 for adjustment. The operation is convenient and safer.
