With the development of construction level, the high-ceiling spaces in shopping malls, hotel lobbies and other areas are getting higher and higher. Elevators have two lifting modes. One is a scissor-arm structure that can achieve lifting and lowering of the horizontal height in the vertical direction, while the other elevator using a rocker arm structure can achieve not only lifting and lowering in the vertical direction but also inclined displacement through the extension and retraction of the rocker arm. For example, a safety elevator for house construction with publication number CN216303215U, the technology of which is: including a pedestal, a rotating table is provided in the middle of the upper surface of the pedestal, the middle of the upper surface of the rotating table is movably connected with a support arm through a pin shaft, the top of the support arm is movably connected with a telescopic arm through a pin shaft, the top of the telescopic arm is movably connected with a connecting arm through a pin shaft, hydraulic rods are sequentially provided between the rotating table, the support arm, the telescopic arm and the connecting arm, and the bottom end of the connecting arm is fixedly connected with a movable plate.

[0003] The above technical solution adopts a lift with a telescopic arm, which can be telescoped along the length direction of the telescopic arm to adjust the installation position. However, when the telescopic arm is extended, the center of gravity of the lift will shift in the direction of extension as the rocker arm is extended. If at this time, the working area of ​​the lift is an uneven area such as a slope, the lift may become unstable or tip over due to the shift of the center of gravity.

[0004] The utility model designs a new technical solution to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a high-stability chassis assembly for an elevator.

[0006] The above technical purpose of the utility model is achieved through the following technical scheme: a high-stability chassis assembly for an elevator, including a turntable and a chassis, the turntable is rotatably connected to the chassis, a number of transmission mechanisms are fixedly connected to the turntable, a number of counterweight blocks are rotatably connected to the transmission mechanism, and a detachable snap-fit ​​structure is provided between the counterweight blocks.

[0007] By adopting the above technical solution, the transmission mechanism can drive the counterweight to slide in a straight line, and the counterweight can be adjusted according to the offset position of the center of gravity of the lifting platform to achieve the center of gravity balance of the elevator. Moreover, the counterweight can be removed and installed at will. When the weight is insufficient, the balance of the elevator can be achieved by adding counterweights.

[0008] The utility model is further configured as follows: a plurality of rotating seats are arranged on the turntable, trapezoidal screw rods are rotatably connected in two relatively coaxial rotating seats, and a counterweight block is threadedly connected to the trapezoidal screw rods.

[0009] By adopting the above technical solution, the rotation of the trapezoidal screw can drive the counterweight block to slide linearly on the trapezoidal screw rod, and the position of the counterweight block can be adjusted according to the direction of the lifting platform.

[0010] The utility model is further configured as follows: the counterweight block includes a fixed counterweight block and a detachable counterweight block, the fixed counterweight block is threadedly connected to the trapezoidal screw rod, and the detachable counterweight block is snap-connected to the fixed counterweight block or the detachable counterweight block.

[0011] By adopting the above technical solution, the user can reduce or increase the number of counterweights according to the actual center of gravity of the elevator to achieve the balance of the elevator.

[0012] The utility model is further configured as follows: fixed seats are fixedly connected to both sides of each rotating seat, a fixing rod is connected between the two fixing seats located on the same side of the rotating seat, and the fixing rod passes through the fixed counterweight block.

[0013] By adopting the above technical solution, after the two sides of the fixed counterweight block are connected by the fixed rod, when the trapezoidal screw rotates and drives the fixed counterweight block to slide linearly, the fixed counterweight block will not rotate with the trapezoidal screw.

[0014] The utility model is further configured as follows: a clamping block is provided on the fixed counterweight block, an embedding groove is provided under the detachable counterweight block, the clamping block and the embedding groove are detachably connected, the clamping block is T-shaped, and both ends of the cross bar on the clamping block are arc-shaped.

[0015] By adopting the above technical solution, the detachable counterweight block can reduce extra counterweight blocks or add new counterweight blocks as needed through the cooperation of the embedding groove and the clamping block. The two ends of the cross bar on the clamping block are arc-shaped so that the clamping block can rotate smoothly in the embedding groove.

[0016] The utility model is further configured as follows: the embedding groove is divided into two layers: a positioning layer and a fixing layer; the positioning layer is consistent in shape with the cross bar on the card block; the space of the fixing layer is circular; and a card groove consistent in shape with the cross bar on the card block is provided on the top of the fixing layer.

[0017] By adopting the above technical solution, the positioning layer is used for preliminary positioning of the card block and the card slot, which has a pre-fixing effect. When the card block reaches the fixing layer, the card block can be finally fixed by rotating the counterweight block 90 degrees and then embedding the card block into the card slot on the top of the fixing layer.

[0018] The utility model is further configured as follows: one end of the trapezoidal screw rod is rotatably connected to a rotating handle.

[0019] By adopting the above technical solution, the user can manually adjust the position of the counterweight by turning the handle to achieve the balance of the overall center of gravity of the elevator.

[0020] To sum up, the utility model has the following beneficial effects: by rotating the handle to drive the rotation of the trapezoidal screw, the counterweight block can slide linearly on the trapezoidal screw. If the gravity of the original counterweight block is insufficient, the detachable clip structure on each detachable counterweight block can be fixed to other counterweight blocks to increase the gravity of the overall counterweight block, thereby achieving the balance of the center of gravity of the elevator and preventing the elevator from tipping over.

DETAILED DESCRIPTION

[0025] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1 , 3 As shown, a high-stability chassis 2 assembly for an elevator includes a turntable 1 and a chassis 2. The turntable 1 is rotatably connected to the chassis 2. A plurality of transmission mechanisms are fixedly connected to the turntable 1. A plurality of counterweight blocks are rotatably connected to the transmission mechanisms. A detachable snap-fit ​​structure is provided between the counterweight blocks.

[0027] like Figure 1 As shown, transmission mechanisms are installed on both sides of the turntable 1, and the transmission mechanisms mainly include a trapezoidal screw 4 and a rotating seat 3. Relatively coaxial rotating seats 3 are provided on both sides of the turntable 1, and a trapezoidal screw 4 is rotatably connected between the relatively coaxial rotating seats 3. A rotating handle 7 is fixedly connected to one end of the trapezoidal screw 4, and the rotating handle 7 makes the trapezoidal screw 4 rotate in the rotating seat 3. Fixed seats 5 are fixed on both sides of each rotating seat 3, and a fixed rod 6 is connected between the relatively coaxial fixed seats 5.

[0028] like Figure 1 , 3 As shown, the counterweight block includes a fixed counterweight block 8 and a removable counterweight block 9. The fixed counterweight block 8 is threadedly connected to the trapezoidal screw 4. The fixed counterweight block 8 can move linearly on the trapezoidal screw 4 through the threaded connection. The above-mentioned fixed rod 6 runs through the fixed counterweight block 8, so that the fixed counterweight block 8 will not rotate with the trapezoidal screw 4 during the movement. The removable counterweight block 9 is used to be installed on the fixed counterweight block 8 or the removable counterweight block 9, and the removable counterweight block 9 can be removed or installed according to the center of gravity of the elevator.

[0029] like Figure 2 , 3 As shown, a clamping block 10 is arranged at the center position of the top surface of the fixed counterweight block 8, and a groove 11 and a clamping block 10 are respectively arranged on the bottom surface and the top surface of the detachable counterweight block 9. The clamping block 10 cooperates with the groove 11 to form a detachable clamping connection. The groove 11 is divided into a positioning layer 111 and a fixing layer 112. The shape of the positioning layer 111 is consistent with the shape of the cross bar on the clamping block 10. The fixing layer 112 is a circular area, which is convenient for the cross bar position of the clamping block 10 to enter the area of ​​the fixing layer 112 and then rotate. A clamping slot 113 is opened on the top of the fixing layer 112, and the clamping slot 113 is embedded with the cross bar on the clamping block 10 to achieve mutual fixation between the counterweight blocks.

[0030] like Figure 1 , 2 As shown in Figure 3, when construction workers encounter an inclined road surface when using a telescopic lift, the lift is prone to tipping over, so the construction workers can turn the handle 7 to drive the rotation of the trapezoidal screw 4, thereby realizing the linear movement of the fixed counterweight 8 on the trapezoidal screw 4. Because of the setting of the fixed rods 6 on both sides, the fixed counterweight 8 will not rotate with the rotation of the trapezoidal screw 4. For example, if the lifting platform is on the left, the center of gravity of the lift will be biased to the left, so sufficient gravity is required on the right side to achieve the balance of the center of gravity of the lift, so the overall counterweight needs to be adjusted to the right side. If the angle of the slope is large, the gravity of the fixed counterweight 8 may not be enough to balance the lift. In order to keep the elevator balanced, removable counterweights 9 can be continuously added to the fixed counterweights 8 to achieve the balance of the elevator. The embedding groove 11 of the removable counterweight 9 is divided into a positioning layer 111 and a fixed layer 112. The positioning layer 111 is only for allowing the card block 10 to be inserted into the embedding groove 11 to play a positioning and pre-fixing effect. Then the card block 10 reaches the position of the fixed layer 112, and the removable counterweight 9 is rotated ninety degrees, and then the card block 10 is embedded in the card groove 113 on the top surface of the fixed layer 112 to achieve the final fixation between the counterweights. If the counterweight needs to be removed, lift the removable counterweight 9, and then rotate it ninety degrees so that the card block 10 can be pulled out of the positioning layer 111.

[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
