[0002] In recent years, the demand for super-large tonnage crawler cranes in nuclear power and petrochemicals has increased, and market competition has become increasingly fierce. While competing on performance and price, the solution of combining two crawler cranes into a crawler crane with a larger tonnage (referred to as a combined vehicle) has quickly been recognized by customers. The existing combined vehicle method requires the addition of some components to meet the needs of combined vehicles, and some single-vehicle components are not used during combined vehicles. For example, the number of counterweight blocks carried by a single vehicle for super-lifting counterweights is relatively small, the number of single layers is small, the length of the counterweight tray is short, and the counterweight tray directly contacts the ground; the number of counterweight blocks carried by the combined vehicle for super-lifting counterweights is large, the number of single layers is large, and the length of the counterweight tray is long, which requires the crawler crane to be connected to get off the vehicle. Since the counterweight tray of a single vehicle is not compatible with the counterweight tray of the combined vehicle, each of the single vehicle and the combined vehicle uses a set of super-lifting counterweight trays, resulting in high cost of use.

[0031] like Figure 8 As shown, the lifting equipment has a movable lower vehicle 700, a platform 710 that can rotate relative to the lower vehicle, and an arm 720 pivotally mounted on the front side of the platform 710. The movable lower vehicle 700 can be a crawler-type or tire-type drive device to provide the lifting equipment with mobility. The platform 710 is rotatably mounted on the movable lower vehicle 700, and the entire weight on the platform 710 can be transferred to the movable lower vehicle 700. A power device is installed on the platform 710, and the power device can rotate the platform 710 through a slewing mechanism. The arm 720 is a multi-section assembled truss structure, and the number of sections can be adjusted as needed to change the length. The lower end of the arm 720 is hinged to the front side of the platform 710.

[0032] Combine the following Figure 1-Figure 7 The specific structure and use method of the weighted tray of the present invention are described.

[0033] Before introducing the structure of the counterweight pallet 800, the existing single-vehicle super-lift counterweight assembly process and the combined vehicle super-lift counterweight assembly process are first introduced. Combining vehicles refers to combining two lifting equipment of the same model into a lifting equipment with a larger lifting capacity.

[0034] like Figure 1 As shown, when the bicycle side tray 610 is used as a bicycle side tray, two bicycle side trays 610 are symmetrically arranged on both sides of the middle tray 620, and the connecting ears of the two bicycle side trays 610 are connected to the connecting ears of the middle tray 620 through a pin shaft, and the middle tray 620 is connected to two hanger bodies 400 through a pin shaft, and the hanger body 400 is connected to the super lifting mast through a pull plate, and the super lifting mast is connected to the main body of the lifting equipment. Since the length of the bicycle super lifting counterweight tray is short, the area of ​​the bicycle super lifting counterweight tray is small, and the number of single-layer counterweight blocks 500 is small, the bicycle super lifting counterweight tray can only carry 9 counterweight blocks 500, and the number of counterweight blocks 500 that can be carried is relatively small.

[0035] like Figure 2As shown, the middle tray 620 of the super-lifting counterweight used in the assembly process of the super-lifting counterweight for the vehicle is longer and can hold two more counterweights 500. The connecting ears of the middle tray 620 of the super-lifting counterweight are connected to the connecting ears of the two side trays 630 through a pin shaft, and the middle tray 620 of the super-lifting counterweight is connected to the four hanger bodies 400 through a pin shaft, and the hanger body 400 is connected to the super-lifting mast through a pull plate, and the super-lifting mast is connected to the main body of the lifting equipment. The side tray 630 on the right is connected to the main body of the lifting equipment through an adjustable support frame 240. Due to the increased area of ​​the assembled counterweight tray, 11 counterweights 500 can be placed.

[0036] like Figures 3 to 5 As shown, the counterweight pallet 800 includes an intermediate pallet 100 and at least two bicycle side pallets 610, the intermediate pallet 100 is provided with a connecting ear assembly, at least two bicycle side pallets, and at least two bicycle side pallets are arranged on the outer periphery of the intermediate pallet 100 and are detachably connected to the intermediate pallet 100 through pins and connecting ear assemblies; wherein the counterweight pallet 800 is indirectly mounted to the rear of the platform 710.

[0037] The counterweight pallet 800 provided by the present invention is configured with a connecting ear assembly on the intermediate pallet 100, and the connecting ear assembly is used to connect the intermediate pallet 100 with at least two single-vehicle side pallets 610 to form a combined counterweight pallet 800. This allows at least two single-vehicle side pallets 610 to be used on the counterweight pallet 800, thereby reducing the number of components required for vehicle assembly, and lowering customer purchase costs as well as material management and transportation costs.

[0038] In one embodiment of the present invention, Figure 3 As shown, the intermediate tray 100 is a rectangular plate-shaped structure, and a plurality of reinforcing beams are arranged in the middle of the intermediate tray 100. The plurality of reinforcing beams are arranged at intervals along the length direction of the intermediate tray 100, and the widths of two adjacent reinforcing beams are equal, and the distances between two adjacent reinforcing beams are equal. Of course, the widths of two adjacent reinforcing beams and the distances between two adjacent reinforcing beams may also be unequal, for example, the reinforcing beams close to the center of the intermediate tray 100 are arranged wider, and the reinforcing beams far from the center of the intermediate tray 100 are arranged narrower; or the reinforcing beams with larger widths and the reinforcing beams with smaller widths are arranged alternately. Of course, the setting method of the width of the reinforcing beams is not limited to this, and is determined according to actual needs.

[0039] Furthermore, if Fig. 9 As shown, the width of the reinforcing beam of the intermediate tray 100 (i.e. Fig. 9 The L in the figure is greater than the width of the reinforcing beam of the bicycle side tray 610. Such a configuration can effectively improve the structural strength of the intermediate tray 100 and ensure that the counterweight tray 800 can hold more counterweight blocks 500.

[0040] In one embodiment of the present invention, Figure 4 As shown, the counterweight pallet 800 includes a first bicycle side pallet 200 and a second bicycle side pallet 300. The first bicycle side pallet 200 and the second bicycle side pallet 300 are both two existing bicycle super-lift counterweight side pallets.

[0041] In one embodiment of the present invention, Figures 3 to 5 As shown, the connecting ear assembly includes a plurality of first connecting ears 110, and the plurality of first connecting ears 110 are arranged at intervals on at least one side of the intermediate tray 100. Specifically, as Figure 3 As shown, first connecting ears 110 are provided on both sides of the intermediate tray 100, and four first connecting ears 110 are provided on each side. The positions of the first connecting ears 110 on both sides correspond to each other, and the first connecting ears 110 are welded and connected to the intermediate tray 100. Of course, the number of first connecting ears 110 is not limited thereto, and is specifically determined according to the length of the intermediate tray 100. The distance between two adjacent first connecting ears 110 is equal, so that each first connecting ear 110 is subjected to balanced force. Of course, the distance between two adjacent first connecting ears 110 may also be unequal, for example, the distance between two first connecting ears 110 close to the middle area of ​​the intermediate tray 100 is smaller, and the distance between two first connecting ears 110 far from the middle area of ​​the intermediate tray 100 is larger. The distance between the two first connecting ears 110 is specifically determined according to the length of the intermediate tray 100 and the weight of the super-lifting counterweight.

[0042] The counterweight pallet 800 includes a first bicycle side pallet 200, which is a rectangular plate body. A plurality of second connecting ears 210 are arranged at intervals on one side of the first bicycle side pallet 200 close to the middle pallet 100. The second connecting ears 210 are used to connect the first bicycle side pallet 200 with the middle pallet 100, and the second connecting ears 210 are detachably connected to the first connecting ears 110 in a one-to-one correspondence.

[0043] Specifically, Figure 4 As shown, four second connecting ears 210 are arranged on the right side of the first bicycle side tray 200 on the left side, and the four second connecting ears 210 are arranged at intervals along the length direction of the intermediate tray 100, that is, the four second connecting ears 210 are arranged at intervals along the up-down direction, and the four second connecting ears 210 are connected to the four first connecting ears 110 on the left side of the intermediate tray 100 through a pin. Similarly, four second connecting ears 210 are arranged on the left side of the first bicycle side tray 200 on the right side, and the four second connecting ears 210 are arranged at intervals along the length direction of the intermediate tray 100, that is, the four second connecting ears 210 are arranged at intervals along the up-down direction, and the four second connecting ears 210 are connected to the four first connecting ears 110 on the right side of the intermediate tray 100 through a pin.

[0044] Preferably, the first connecting ear 110 is a double connecting ear structure, and the intermediate pallet 100 is connected to the first bicycle side pallet 200 using the double connecting ear structure, which effectively improves the connection strength between the intermediate pallet 100 and the first bicycle side pallet 200 and enhances the stability of the counterweight pallet 800.

Figure 4 As shown, two third connecting ears 120 are provided at both ends of the intermediate pallet 100, and the third connecting ears 120 are welded to the intermediate pallet 100. The two third connecting ears 120 at the same end are arranged at intervals along the width direction of the intermediate pallet 100, and the third connecting ears 120 at both ends of the intermediate pallet 100 are symmetrically arranged. In this way, during the assembly process, even if the intermediate pallet 100 is rotated 180° in the horizontal direction, it can also be assembled normally without affecting the use of the counterweight pallet.

[0046] Preferably, the third connecting ear 120 is a double connecting ear structure, and the intermediate pallet 100 is connected to the second bicycle side pallet 300 using the double connecting ear structure, which effectively improves the connection strength between the intermediate pallet 100 and the second bicycle side pallet 300 and enhances the stability of the counterweight pallet 800.

[0047] The counterweight tray 800 includes a second bicycle side tray 300, and a plurality of fourth connecting ears 310 are arranged at intervals on one side of the second bicycle side tray 300 close to the middle tray 100, and some of the fourth connecting ears 310 are detachably connected to the corresponding third connecting ears 120. Figure 4 As shown, the second bicycle side tray 300 is a rectangular plate body, and four fourth connecting ears 310 are arranged at intervals on one side of the second bicycle side tray 300 located at the top close to the middle tray 100. The fourth connecting ears 310 are welded and connected to the second bicycle side tray 300. The four fourth connecting ears 310 are arranged at intervals along the length direction of the second bicycle side tray 300 at the top, that is, the four fourth connecting ears 310 are arranged at intervals along the left-right direction, and the distance between two adjacent fourth connecting ears 310 is equal. Of course, the distance between two adjacent fourth connecting ears 310 may also be unequal. Among the four fourth connecting ears 310, the positions of the two fourth connecting ears 310 located in the middle correspond to the positions of the two third connecting ears 120 at the upper end of the middle tray 100 one by one, and the two fourth connecting ears 310 in the middle are connected to the two third connecting ears 120 at the upper end of the middle tray 100 one by one through a pin shaft.

[0048] Similarly, four fourth connecting ears 310 are arranged at intervals on one side of the second bicycle side tray 300 located below and close to the middle tray 100. The fourth connecting ears 310 are welded and connected to the second bicycle side tray 300 below. The four fourth connecting ears 310 are arranged at intervals along the length direction of the second bicycle side tray 300 below, that is, the four fourth connecting ears 310 are arranged at intervals along the left-right direction, and the distance between two adjacent fourth connecting ears 310 is equal. Of course, the distance between two adjacent fourth connecting ears 310 may also be unequal. Among the four fourth connecting ears 310, the positions of the two fourth connecting ears 310 located in the middle correspond to the positions of the two third connecting ears 120 at the lower end of the middle tray 100 one by one, and the two fourth connecting ears 310 in the middle are connected to the two third connecting ears 120 at the lower end of the middle tray 100 one by one through a pin shaft.

[0049] In one embodiment of the present invention, Figure 4 As shown, at least one end of the first bicycle side tray 200 is provided with a lateral connection ear 220, and the lateral connection ear 220 is used to connect the first bicycle side tray 200 and the second bicycle side tray 300, and the remaining fourth connection ears 310 are detachably connected to the corresponding lateral connection ears 220, and the sum of the number of the lateral connection ears 220 and the number of the third connection ears 120 is equal to the number of the fourth connection ears 310. Specifically, as Figure 3 As shown, both ends of the first bicycle side tray 200 are provided with a lateral connection ear 220. Of course, the number of the lateral connection ears 220 is not limited thereto, and is specifically determined according to the number of the third connection ears 120 and the number of the fourth connection ears 310.

[0050] The lateral connection ear 220 at the upper end of the left first bicycle side tray 200 is connected to the fourth connection ear 310 at the left end of the second bicycle side tray 300 above through a pin; the lateral connection ear 220 at the lower end of the left first bicycle side tray 200 is connected to the fourth connection ear 310 at the left end of the second bicycle side tray 300 below through a pin. Similarly, the lateral connection ear 220 at the upper end of the right first bicycle side tray 200 is connected to the fourth connection ear 310 at the right end of the second bicycle side tray 300 above through a pin; the lateral connection ear 220 at the lower end of the right first bicycle side tray 200 is connected to the fourth connection ear 310 at the right end of the second bicycle side tray 300 below through a pin.

[0051] Preferably, the lateral connecting ear 220 is a double connecting ear structure, and the first bicycle side pallet 200 is connected to the second bicycle side pallet 300 using the double connecting ear structure, which effectively improves the connection strength between the first bicycle side pallet 200 and the second bicycle side pallet 300 and enhances the stability of the counterweight pallet 800.

[0052] In one embodiment of the present invention, a counterweight is stacked on top of the counterweight tray 800 to form a counterweight assembly; wherein the counterweight assembly is used to balance a portion of the load of the lifting equipment.

Preferably, the width and thickness of the two first bicycle side pallets 200 are equal, and such an arrangement can facilitate the production of the first bicycle side pallets 200, thereby improving the production efficiency.

[0054] In one embodiment of the present invention, Figure 4 As shown, a support frame connecting ear 230 is provided on one side of the first bicycle side pallet 200 away from the middle pallet 100, and the support frame connecting ear 230 is connected to the main body of the lifting equipment through an adjustable support frame 240. Specifically, as Figure 3 As shown, two support frame connecting ears 230 are provided on the side of the first bicycle side pallet 200 on the right side away from the middle pallet 100. The two support frame connecting ears 230 are arranged at intervals along the length direction of the middle pallet 100.

Specifically, Figure 4 As shown, one of the two second bicycle side pallets 300 is located at the top and the other is located at the bottom. The two second bicycle side pallets 300 are symmetrically arranged at both ends of the middle pallet 100. The length, width and thickness of the two second bicycle side pallets 300 are equal; the two ends of the second bicycle side pallets 300 are aligned with the side of the two first bicycle side pallets 200 away from the middle pallet 100, so that a rectangular pallet can be formed, such as Figure 7 As shown, the counterweight tray can hold 15 counterweight blocks 500 in one layer.

[0056] In one embodiment of the present invention, a bottom connecting ear (not shown) is provided at the bottom of the intermediate pallet 100. Preferably, two bottom connecting ears are provided at intervals, and the bottom connecting ears are connected to the transition platform. Since the intermediate pallet 100 needs to be connected to the transition platform through the bottom connecting ear to realize walking with the super-lift counterweight track, it cannot be directly compatible with the intermediate pallet of a single vehicle, but it can be compatible with the intermediate counterweight pallet by adding a transition section on the basis of the intermediate pallet of the single vehicle.

[0058] The weighted tray 800 provided by the present invention is as follows: Figure 7 As shown, the super-lifting counterweight pallet of a single vehicle is used, and after being combined, it is used on the super-lifting pallet of the combined vehicle. The middle pallet 100 is connected with at least two single-vehicle side pallets 610 by a connecting ear assembly to form a combined counterweight pallet 800, which reduces the number of parts required for the combined vehicle, reduces the cost of four side pallets by about 900,000 yuan, and reduces the purchase cost and the material management and transportation cost. In addition, the combined super-lifting counterweight pallet can hold 15 counterweight blocks 500 per layer, which is 4 more counterweight blocks 500 than the existing super-lifting counterweight pallet per layer. The structural form has better load-bearing capacity and can be equipped with more counterweight blocks 500.

[0059] The present invention also provides a counterweight assembly, wherein the lifting equipment comprises a counterweight and the counterweight pallet 800 described in any one of the above embodiments, and a counterweight is stacked on top of the counterweight pallet 800 to form a counterweight assembly.
