Description

Technical Field

[0001] The utility model belongs to the technical field of crawler vehicles and relates to a counterweight tower for a crawler vehicle. Background Art

[0002] During the test run of the tracked armored vehicle prototype, in order to verify the vehicle driving test, it is necessary to install related components such as the turret. However, the turret and other related components are expensive. In order to save the test cost, while ensuring the overall weight of the vehicle, a counterweight tower that completely simulates the turret is used to replace the turret, which becomes a necessary and feasible solution.

[0003] At present, the counterweight tower of armored vehicles has a simple structure. A cylindrical storage container is directly welded on the turret seat ring, and counterweights such as sandbags are stacked in the storage container.

[0004] The cylindrical storage counterweight tower, with its sandbags stacked loosely inside, caused them to fly around while the vehicle was moving, destabilizing the vehicle's center of gravity. Because the existing counterweight tower lacked a seal above it, the sandbags, washed away by rain, easily rusted the iron sand, leaving the tower's interior messy and unsightly, affecting its overall aesthetic. Utility Model Content

[0005] The purpose of this utility model is to provide a counterweight tower for tracked vehicles that replaces a turret while ensuring the center of mass remains unchanged, for use in test runs. The counterweight tower is installed in the same position as the turret and is fixed in the same manner as the turret. The counterweight tower has the advantages of a mature production process, high production efficiency, easy installation and disassembly, and high interchangeability between identical counterweights. Because the counterweights are fixed within a confined frame, they are not prone to slipping, providing a high level of safety. The entire structure is sealed, ensuring that the counterweights and tower are not affected by rain and will not rust.

[0006] The technical solutions adopted in this utility model are as follows:

[0007] A tracked vehicle counterweight tower comprises a frame assembly (1), a left-side entrance and exit cover (2), a right-side entrance and exit cover (3), a counterweight cover plate (4), a counterweight block 1 (6), a counterweight block 2 (7) and a counterweight block 3 (8);

[0008] The frame assembly (1) is fixed on the turret seat ring; the frame assembly is a cavity structure, consisting of compartments and a bottom plate, and the compartments are sequentially divided from left to right into a left outer compartment, a left compartment, a middle compartment, a right compartment and a right outer compartment; a mounting hole is opened on the bottom plate of the frame assembly, the lower ends of the middle compartment, the left compartment and the right compartment extend out of the mounting hole, and the bottom ends of the left outer compartment and the right outer compartment are welded to the upper surface of the bottom plate;

[0009] Three counterweights (8) are placed in the left outer compartment and the right outer compartment, two counterweights (7) are placed in the compartments of the left and right compartments, and one counterweight (6) is placed in the compartment of the middle compartment;

[0010] Two entrances and exits are symmetrically provided on the bottom plate, and the two entrances and exits are respectively located on the upper and lower sides of the middle compartment; a left entrance and exit cover (2) and a right entrance and exit cover (3) are installed on the upper and lower sides of the frame assembly and located above the two entrances and exits, providing an operator with access to the vehicle body to perform other test operations;

[0011] The counterweight cover plate (4) is fixed to the upper end of the frame assembly and covers the upper part of the compartment.

[0012] Preferably, the counterweight cover plate (4) is fixed above the compartment with bolts.

[0013] Preferably, a threaded hole is formed on the upper end of each counterweight block, and a hook (5) can be installed.

[0014] Preferably, the weight of the counterweight (8) is 100 kg, the weight of the counterweight (7) is 200 kg and the weight of the counterweight (6) is 300 kg.

[0015] Preferably, after the counterweight block and the counterweight cover plate are installed on the frame assembly, the ratio of the mass above the frame assembly bottom plate to the mass below the frame assembly bottom plate is 3:2.

[0016] Preferably, the maximum overall counterweight mass can reach 16,000 kg.

[0017] Preferably, the frame assembly is 7000 kg + 9000 kg counterweight.

[0018] Preferably, the frame assembly (1) is fixed to the vehicle body turret seat ring with bolts and nuts.

[0019] Preferably, the counterweight is inserted into the corresponding compartment of the frame assembly (1) by a crane.

[0020] Preferably, the counterweight installation interface is unified.

[0021] Beneficial effects of the utility model:

[0022] The advantages of this utility model are that the counterweight tower replaces the traditional method of using sandbags and other loose counterweights, firmly fixing the counterweights in the corresponding compartments, solidifying the center of mass of the entire vehicle. Larger counterweights can replace turrets of different masses. The counterweight tower changes the previous counterweight installation method, hoisting the counterweight block, improving counterweight efficiency, reducing operator labor intensity, and improving operator safety.

[0030] The present invention will be described in further detail below with reference to the accompanying drawings.

[0031] like Figures 1 to 7 As shown, the counterweight tower provided by the utility model mainly consists of a frame assembly (1), a left side entrance and exit cover (2), a right side entrance and exit cover (3), a counterweight cover plate (4), a counterweight block 1 (6), a counterweight block 2 (7) and a counterweight block 3 (8).

[0032] The frame assembly (1) is fixed on the turret seat ring by bolts and nuts.

[0033] like Figure 5 、 Figure 6 As shown, the frame assembly is a cavity structure, consisting of compartments and a bottom plate. The compartments are sequentially partitioned from left to right into a left outer compartment, a left compartment, a middle compartment, a right compartment and a right outer compartment.

[0034] The frame assembly bottom plate is provided with mounting holes, the lower ends of the middle compartment, the left compartment and the right compartment extend out of the mounting holes, and the bottom ends of the left outer compartment and the right outer compartment are welded to the upper surface of the bottom plate.

[0035] Three counterweight blocks (8) are placed in the left outer compartment and the right outer compartment, two counterweight blocks (7) are placed in the compartments of the left compartment and the right compartment, and one counterweight block (6) is placed in the compartment of the middle compartment.

[0036] Two entrances and exits are symmetrically opened on the bottom plate, and the two entrances and exits are respectively located on the upper and lower sides of the middle compartment. The left entrance and exit cover (2) and the right entrance and exit cover (3) are installed on the upper and lower sides of the frame assembly and located above the two entrances and exits, providing operators with access to the vehicle body to perform other test operations.

[0037] like Figure 1 As shown, the counterweight cover plate (4) is fixed to the upper end of the frame assembly by bolts, covering the upper part of the compartment.

[0038] like Figure 7 As shown, each counterweight block has a threaded hole on its upper end for mounting a hook (5).

[0039] The installation sequence of the counterweight tower is as follows:

[0040] 1 Fix the frame assembly (1) to the turret seat ring of the vehicle body with bolts and nuts.

[0041] 2 Use the hook (5) to install the counterweight blocks respectively, insert the counterweight blocks into the corresponding compartments of the frame assembly (1) by using a crane, then remove the hook (5) and install it on the next counterweight block. After the required counterweight blocks are completely installed, remove the hook (5).

[0042] 3. Fix the counterweight cover (4) on top of the compartment with bolts.

[0043] The counterweight tower of this utility model has the following key points:

[0044] 1. Structural features: The overall structure is sealed, utilizing the weight of the counterweight cover to limit the up and down movement of the counterweight. This seal prevents rainwater from entering the counterweight tower. Partitions restrict the forward, backward, left, and right movement of the counterweight, securing it securely within the frame assembly. The overall sealed design prevents rainwater from entering the counterweight tower and causing rust.

[0045] 2. After rigorous calculations and on-site verification, after the counterweight block and counterweight cover are installed on the frame assembly, the ratio of the mass above the frame assembly floor to the mass below the frame assembly floor is 3:2, which fully simulates the center of mass position of the turret and the entire vehicle, ensuring that the counterweight tower fully meets all test conditions of the entire vehicle after installation.

[0046] 3. The mass of the counterweight blocks is divided into three specifications: counterweight block (8) 100 kg, counterweight block (7) 200 kg and counterweight block (6) 300 kg. The maximum mass of the overall counterweight can reach 16,000 kg. The frame assembly is 7,000 kg + 9,000 kg counterweight, which can replace turrets of various masses.

[0047] 4. The counterweight block has a unified installation interface, which is convenient for installation and removal. The counterweight ratio can be adjusted in time to make the counterweight ratio more reasonable. The counterweight block is fixedly installed to stabilize the center of gravity of the vehicle.
