Description

TECHNICAL FIELD

[0001] The utility model relates to a locking mechanism, in particular to a counterweight locking mechanism. BACKGROUND

[0002] In engineering construction, mechanical manufacturing and many other fields, counterweights are widely used to balance equipment weight, adjust the center of gravity and ensure stable operation of the equipment. However, in actual operation, the handling and storage of counterweights face a series of problems.

[0003] Locking and fixing problem: In the prior art, the locking and fixing method for counterweights in the stacked state is single and ineffective. The common fixing method is often complex in structure and cumbersome to operate, requiring a lot of manpower and time cost. Moreover, during actual movement or transportation, these fixing methods cannot effectively prevent the counterweights from shifting and falling, increasing the safety hazard. For example, some simple rope binding methods are prone to looseness when encountering bumps or vibrations, which cannot guarantee the stability of the counterweights.

[0004] Overall locking effect problem: When multiple counterweights need to be stacked, the existing device is difficult to effectively lock and fix multiple counterweights at the same time. Often, some counterweights cannot be fixed firmly, which greatly reduces the stability of the entire stack. This not only affects work efficiency, but also may cause safety accidents in subsequent use, such as counterweights falling and damaging equipment or causing personnel casualties.

[0005] Inconvenient use and poor effect: Due to the lack of effective overall locking scheme, in actual application scenarios, operators have to spend extra effort to check and adjust the fixed state of each counterweight, increasing the workload. Moreover, even after repeated checks, it is still difficult to ensure the safety of the counterweights during the entire handling and storage process, resulting in unsatisfactory use effect and inability to meet actual work requirements.

[0006] In view of the above problems existing in the prior art, it is of great practical significance to develop a device with simple structure, convenient use, which can effectively lock and fix counterweights in the stacked state, and ensure the overall locking effect of multiple counterweights.

[0022] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0023] Please refer to Figs. 1-3 A counterweight locking mechanism, including fixed bottom plate 1, fixed bottom plate 1 top fixedly connected with outer frame 2, the fixed bottom plate 1 top fixedly connected with support seat 3, counterweight is placed on support seat 3 top, the outer frame 2 inner side slidingly connected with sliding clamping plate 4, support seat 3 is fixedly connected with the bottom drive mechanism 5 of driving sliding clamping plate 4 clamping, sliding clamping plate 4 is fixedly connected with clamping assembly 6.

[0024] When in use, the weight blocks are placed above the supporting seat 3, and then the clamping of the weight blocks can be realized through the cooperation of the bottom driving mechanism 5 and the clamping assembly 6.

[0025] The bottom driving mechanism 5 comprises a driving screw 7, the screw threads of the two ends of the driving screw 7 are opposite, the driving screw 7 is threadedly connected with the sliding clamping plate 4, and the middle part of the driving screw 7 is fixedly connected with a first gear 8. A rack 9 for driving the first gear 8 to rotate is slidingly connected above the fixed bottom plate 1. A driving handle 10 is rotatably connected above the fixed bottom plate 1, and the middle part of the handle is rotatably connected with the end part of the rack 9 through a transmission connecting rod 11.

[0026] Before the weight blocks are placed, the driving handle 10 needs to be lifted first. After the driving handle 10 is lifted, the rack 9 is driven to move backward, the first gear 8 is driven to rotate in the process that the rack 9 moves backward, the driving screw 7 is driven to rotate by the first gear 8, and then the driving screw 7 is driven to drive the sliding clamping plate 4 to move outward under the action of the screw threads, and the clamping assembly 6 connected with the sliding clamping plate 4 is simultaneously driven to move outward, so that the placement of the weight blocks is facilitated.

[0027] The clamping assembly 6 comprises clamping screws 12 which are threadedly connected with the sliding clamping plate 4, the screw threads of the clamping screws 12 are opposite, there are two clamping screws 12 which are symmetrically arranged on the sliding clamping plate 4, the inner ends of the clamping screws 12 are rotatably connected with a clamping base plate 13, the outer ends of the clamping screws 12 are fixedly connected with second gears 14, the two second gears 14 are meshed with each other, and the outer end face of one of the second gears 14 is fixedly connected with a rotating handle 15.

Then the rotating handle 15 is rotated to enable the clamping assembly 6 to clamp each weight block. The rotating of the rotating handle 15 drives the second gears 14 to rotate, the second gears 14 drive the clamping screws 12 to move inward synchronously in the rotating process, the clamping base plate 13 moves inward, and the clamping rods 16 connected with the clamping base plate 13 clamp each weight block.

Before placing the counterweight block, the driving handle 10 needs to be lifted first. After the driving handle 10 is lifted, the rack 9 is driven to move backward, the first gear 8 is rotated during the backward movement of the rack 9, the driving screw 7 is rotated by the rotation of the first gear 8, and then the driving screw 7 is driven to slide outward by the force of the thread, synchronously driving the clamping assembly 6 connected with the sliding clamping plate 4 to move outward, facilitating the placement of the counterweight block. After the counterweight block is placed, the driving handle 10 is pulled in the reverse direction, the driving handle 10 drives the rack 9 to move forward through the transmission connecting rod 11, the first gear 8 is reversely rotated, the sliding clamping plate 4 is moved inward, and preliminary clamping is realized. Then, the rotary knob 15 is rotated to clamp each counterweight block. The rotation of the rotary knob 15 drives the second gear 14 to rotate, the second gear 14 rotates during the movement of the clamping screw 12, and the clamping base plate 13 moves inward, so that the clamping rod 16 connected with the clamping base plate 13 clamps each counterweight block. Since each clamping rod 16 is independent, it can independently clamp different counterweight blocks and will not cause the situation that some counterweight blocks are not clamped in place. The spring 17 provides the clamping force.
