Description

Technical Field

[0001] This utility model belongs to the field of hoisting technology, and in particular relates to a crawler crane lifting pallet. Background Technology

[0002] The existing operation process for crawler crane superlift is as follows: Strictly following the key parameters in the lifting plan, the crawler crane (excluding the superlift mechanism) travels to the work position; the truck crane lifts the counterweights piece by piece onto the flatbed truck, then the superlift pallet blocks are lifted onto the counterweights or into the empty area of ​​the flatbed truck; the flatbed truck transports the pallet and counterweights to the rear of the crawler crane; the truck crane unloads the superlift pallet; the superlift pallet is installed (the pallet is connected to the two lifting cylinder A-type connecting frames via pins, and the A-type connecting frames are hinged to the top plate of the horizontal guide frame to ensure that the entire superlift pallet is connected to the crawler crane's upper body via the A-type connecting frames and the horizontal guide frame, and connected to the superlift mast via the connecting plate); the counterweights on the flatbed truck are lifted piece by piece onto the crawler crane's superlift pallet; wire ropes and shackles are used to connect the crawler crane hook head and the load being lifted; a trial lift is performed, and the lifting operation begins.

[0003] The entire process of lifting and unloading the superlift counterweight occupies both the truck crane and flatbed truck, leaving the crawler crane idle throughout the installation and dismantling of the superlift counterweight. When the crawler crane needs to be moved to the next lifting task, the superlift counterweight and superlift pallet must be removed, and the crawler crane alone must travel to the next work location according to the lifting plan. The flatbed truck transports the counterweight blocks and superlift pallet to the rear of the crawler crane, the superlift pallet is installed, and then the truck crane is used to assemble the required counterweight blocks one by one onto the superlift pallet. When using the existing superlift operating conditions, there is a high equipment usage time, slow crawler crane relocation, high construction costs, and a high risk of collision when loading and unloading superlift counterweight blocks.

[0004] Therefore, there is an urgent need to design a crawler crane that can lift pallets to solve the problems mentioned above. Utility Model Content

[0005] To address the technical problems mentioned in the background art, such as the high operating time of existing superlift equipment, slow site transfer of crawler cranes, high construction costs, and high collision risk during loading and unloading of superlift counterweights, a crawler crane superlift pallet is provided to solve the problem of reducing the loading and unloading time of crawler crane superlift counterweights.

[0006] To achieve the above objectives, the specific technical solution for the tracked crane's overlift pallet of this utility model is as follows: A crawler crane lifting pallet includes longitudinal support beams with equal spacing between adjacent longitudinal support beams. Multiple transverse support beams are connected at intervals along the length of the longitudinal support beams. A longitudinal reinforcing beam is connected between adjacent transverse support beams. A longitudinal side beam is connected to the side of the transverse support beam away from the longitudinal reinforcing beam. A transverse pallet panel and a longitudinal pallet panel are connected at intervals on the longitudinal and transverse support beams. Both the transverse and longitudinal pallet panels are provided with pallet limiting blocks, which abut against counterweight blocks to ensure that the counterweight blocks are positioned on the transverse and longitudinal pallet panels. Support columns are connected to the connection nodes of the longitudinal support beams on both sides and the transverse side beams; a connecting plate is installed on the longitudinal reinforcing beam, and the connecting plate is hinged to the crawler crane A-frame so that the counterweight block is placed on the crawler crane.

[0007] Furthermore, the longitudinal support beam includes a first longitudinal support beam, a second longitudinal support beam, and a third longitudinal support beam arranged sequentially, with the first longitudinal support beam, the second longitudinal support beam, and the third longitudinal support beam being parallel to each other.

[0008] Furthermore, the transverse support beam includes a first transverse support beam, a second transverse support beam, a third transverse support beam, and a fourth transverse support beam. The two ends of the first transverse support beam, the second transverse support beam, the third transverse support beam, and the fourth transverse support beam are all vertically connected to the first longitudinal support beam and the third longitudinal support beam.

[0009] Furthermore, multiple transverse side beams are vertically connected to both the first and third longitudinal support beams, so that the transverse side beams are aligned with the first, second, third, and fourth transverse support beams.

[0010] Furthermore, longitudinal reinforcing beams are vertically and intermittently connected between the first transverse support beam and the second transverse support beam, and between the third transverse support beam and the fourth transverse support beam.

[0011] Furthermore, both the second and third transverse support beams are vertically provided with connecting cantilever beams on the side away from the longitudinal reinforcing beam, so that the connecting plate is placed on the connecting cantilever beam.

[0012] Furthermore, the connecting plate is provided with a shaft hole reinforcing plate, which is hinged to the crawler crane A-frame so that the counterweight block is connected to the crawler crane.

[0013] Furthermore, both the first and third longitudinal support beams are connected at intervals and vertically to support columns. The support columns are vertically connected to an upper base plate on the side away from the first or third longitudinal support beam. The upper base plate is connected to a lower base plate through a vertical plate, and the lower base plate rests on the ground.

[0014] Furthermore, the upright plate is vertically connected between the upper and lower base plates so that the centers of the supporting column, upper base plate, upright plate, and lower base plate are aligned in a straight line.

[0015] Furthermore, a stiffening rib connects the upper and lower base plates, with one side of the stiffening rib vertically connected to the upright plate.

[0016] The tracked crane pallet lifting device of this utility model has the following advantages: The main frame of the pallet is formed by connecting longitudinal and transverse support beams. Transverse and longitudinal pallet panels are connected to the longitudinal and transverse support beams to set pallet limit blocks, thereby placing and limiting the counterweight blocks. When using a superlift pallet, an SPMT vehicle transports the superlift pallet to the crawler crane, connecting the crawler crane's A-frame to the superlift pallet for lifting operations. This application reduces the time spent using flatbed trucks and the number of truck crane shifts during superlift counterweight block loading and unloading, improving the efficiency of superlift counterweight block loading and unloading, and significantly reducing the shift costs for changing superlift operating conditions of large crawler cranes. Simultaneously, the counterweight area is located around the A-frame, reducing the risk of collisions during counterweight loading and unloading. Attached Figure Description

For example, in the claims, any of the claimed embodiments can be used in any combination.

[0021] The following is a reference to the appendix. Figure 1 To be continued Figure 7 This invention describes the tracked crane lifting pallet of the present invention.

[0022] like Figure 1 and Figure 7 As shown, the crawler crane lifting pallet of this utility model includes a longitudinal support beam 1, with the same spacing between adjacent longitudinal support beams 1. Multiple transverse support beams 2 are connected at intervals along the length direction of the multiple longitudinal support beams 1. A longitudinal reinforcing beam 3 is connected between adjacent transverse support beams 2. A longitudinal side beam 5 is connected to the side of the transverse support beam 2 away from the longitudinal reinforcing beam 3. A transverse pallet panel 6 and a longitudinal pallet panel 7 are connected at intervals on the longitudinal support beams 1 and the transverse support beams 1. Both the transverse pallet panel 6 and the longitudinal pallet panel 7 are provided with pallet limiting blocks 16. The pallet limiting blocks 16 abut against the counterweight blocks 17 so that the counterweight blocks 17 are set on the transverse pallet panel 6 and the longitudinal pallet panel 7. Support columns 11 are connected to the connection nodes of the longitudinal support beams 1 on both sides and the transverse side beams 4; a connecting plate 9 is provided on the longitudinal reinforcing beam 3, and the connecting plate 9 is hinged to the crawler crane A-frame so that the counterweight block 17 is placed on the crawler crane.

[0023] The main frame of the pallet is formed by connecting the longitudinal support beam 1 and the transverse support beam 2. The transverse pallet panel 6 and the longitudinal pallet panel 7 are connected to the longitudinal support beam 1 and the transverse support beam 2 to set the pallet limiting block 16, thereby placing and limiting the counterweight block 17. When using the super-lift pallet, the SPMT vehicle transports the super-lift pallet to the bottom of the crawler crane, so that the A-frame of the crawler crane is connected to the super-lift pallet, and the lifting operation can be carried out.

[0024] Furthermore, such as Figure 1As shown, the longitudinal support beam 1 includes a first longitudinal support beam 101, a second longitudinal support beam 102, and a third longitudinal support beam 103 arranged sequentially, with the first longitudinal support beam 101, the second longitudinal support beam 102, and the third longitudinal support beam 103 parallel to each other; the transverse support beam 2 includes a first transverse support beam 201, a second transverse support beam 202, a third transverse support beam 203, and a fourth transverse support beam 204, with both ends of the first transverse support beam 201, the second transverse support beam 202, the third transverse support beam 203, and the fourth transverse support beam 204 vertically connected to the first longitudinal support beam 101 and the third longitudinal support beam 103; multiple transverse side beams 4 are vertically connected to the first longitudinal support beam 101 and the third longitudinal support beam 103, so that the transverse side beams 4 are located on the same straight line as the first transverse support beam 201, the second transverse support beam 202, the third transverse support beam 203, and the fourth transverse support beam 204.

[0025] In this embodiment, preferably, the first longitudinal support beam 101, the second longitudinal support beam 102, and the third longitudinal support beam 103 have the same shape and size, and the spacing between the first longitudinal support beam 101, the second longitudinal support beam 102, and the third longitudinal support beam 103 is the same, that is, the first longitudinal support beam 101 and the third longitudinal support beam 103 are located on both sides of the second longitudinal support beam 102.

[0026] The first transverse support beam 201, the second transverse support beam 202, the third transverse support beam 203, and the fourth transverse support beam 204 are sequentially and vertically welded to the first longitudinal support beam 101, the second longitudinal support beam 102, and the third longitudinal support beam 103, ensuring that the first transverse support beam 201 and the second transverse support beam 202 are located on one side, and the third transverse support beam 203 and the fourth transverse support beam 204 are located on the other side, thereby forming the main frame of the lifting pallet.

[0027] Preferably, transverse side beams 4 are vertically welded to the outer sides of both the first longitudinal support beam 101 and the third longitudinal support beam 103, ensuring that the transverse side beams 4 on both sides are on the same straight line as the first transverse support beam 201, the second transverse support beam 202, the third transverse support beam 203 and the fourth transverse support beam 204, thereby strengthening the overall rigidity of the lifting pallet.

[0028] Furthermore, such as Figure 1 As shown, longitudinal reinforcing beams 3 are vertically and intermittently connected between the first transverse support beam 201 and the second transverse support beam 202, and between the third transverse support beam 203 and the fourth transverse support beam 204; connecting cantilever beams 8 are vertically provided on the side of the second transverse support beam 202 and the third transverse support beam 203 away from the longitudinal reinforcing beams 3, so that the connecting plate 9 is placed on the connecting cantilever beam 8; the connecting plate 9 is provided with a shaft hole reinforcing plate 10, which is hinged to the crawler crane A-frame so that the counterweight block 19 is connected to the crawler crane.

[0029] In this embodiment, preferably, a longitudinal reinforcing beam 3 is welded perpendicularly and spaced between the first transverse support beam 201 and the second transverse support beam 202, and a longitudinal reinforcing beam 3 is welded perpendicularly and spaced between the third transverse support beam 203 and the fourth transverse support beam 204, and the longitudinal reinforcing beam 3 between the first transverse support beam 201 and the second transverse support beam 202 and the longitudinal reinforcing beam 3 between the third transverse support beam 203 and the fourth transverse support beam 204 are located on a straight line.

[0030] The second transverse support beam 202 and the third transverse support beam 203 are both vertically welded with connecting cantilever beams 8 on the side away from the longitudinal reinforcing beam 3. The connecting cantilever beams 8 and the longitudinal reinforcing beam 3 are on the same straight line. A connecting plate 9 is welded on the connecting cantilever beam 8. The connecting plate 9, which is equipped with a shaft hole reinforcing plate 10, is connected to the crawler crane A-frame by a pin shaft.

[0031] Furthermore, such as Figures 1 to 6 As shown, support columns 11 are spaced apart and vertically connected to the first longitudinal support beam 101 and the third longitudinal support beam 103. An upper base plate 12 is vertically connected to the side of the support column 11 away from the first longitudinal support beam 101 or the third longitudinal support beam 103. The upper base plate 12 is connected to the lower base plate 13 through a vertical plate 14. The vertical plate 14 is vertically connected between the upper base plate 12 and the lower base plate 13 so that the centers of the support columns 11, the upper base plate 12, the vertical plate 14 and the lower base plate 13 are on a straight line. A stiffening plate 15 is connected between the upper base plate 12 and the lower base plate 13. One side of the stiffening plate 15 is vertically connected to the vertical plate 14.

[0032] In this embodiment, preferably, support columns 11 are vertically welded below both ends of the first longitudinal support beam 101 and the third longitudinal support beam 103 to support the entire lifting pallet; at the same time, an upper base plate 12 is vertically welded to the end of the support column 11, and a vertical plate 14 is vertically welded to the side of the upper base plate 12 away from the support column 11, and the vertical plate 14 is vertically welded to the lower base plate 13.

[0033] Meanwhile, multiple stiffening plates 15 are vertically welded between the upper base plate 12 and the lower base plate 13. One side of the stiffening plate 15 is vertically welded to the upright plate 14, thereby ensuring the overall steel strength of the lifting pallet.

[0034] The working principle of the tracked crane lifting pallet in this utility model is as follows: When the crawler crane needs to perform superlift operations, connect the pin on the A-frame of the lifting cylinder of the crawler crane to the shaft hole reinforcement plate 10 of the superlift pallet. Use a truck crane to install and stack the counterweight 17 on the superlift pallet fixture. The flatbed truck or SPMT truck drives into the bottom of the superlift pallet and moves the superlift pallet with the counterweight 17 installed to the rear of the crawler crane. After that, lower the entire superlift pallet and leave. Adjust the lifting cylinder lifting A-frame connecting rod, or lift the flatbed truck / SPMT truck, so that the lifting cylinder A-frame is connected to the end pin of the horizontal guide frame. Then the lifting operation can begin.

[0035] When the superlift counterweight is light, a flatbed truck can be used to move the superlift pallet; when the superlift counterweight is heavy and exceeds the rated load of the flatbed truck, a SPMT truck can be used to complete the moving work.

[0036] Based on the crawler crane's super-lift pallet, this utility model reduces the time occupied by the flatbed truck when loading and unloading the super-lift counterweight, as well as the truck crane shift when unloading the counterweight 17, thereby improving the loading and unloading efficiency of the super-lift counterweight and greatly reducing the shift cost of changing the super-lift working conditions of large crawler cranes; at the same time, the counterweight area is set outside the A-frame, reducing the collision risk when loading and unloading the counterweight.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
