Description

Technical Field

[0001] The utility model relates to the technical field of logistics conveying equipment, in particular to a counterweight structure of a heavy-duty elevator. Background Art

[0002] Reciprocating elevator is a heavy-duty conveying equipment used for vertical transportation of goods. Its cargo platform is generally hung on one end of the transmission chain, and a counterweight is hung on the other end of the transmission chain. The function of the counterweight is to balance the gravity of the cargo platform to reduce the load of the drive motor. For heavy-duty elevators, since the lifted goods are heavier, heavier counterweights are used for balance.

[0003] The Chinese utility model patent with authorization announcement number CN218114896U discloses a counterweight device for a reciprocating hoist, including a counterweight frame and a counterweight block. The counterweight block is located in the counterweight frame. A limit member and a limit rod are arranged inside the counterweight frame. The limit members are symmetrically arranged on both sides of the counterweight block. The counterweight block is sleeved on the limit rod and the counterweight block is limited and clamped by a clamping nut. However, since the counterweight block is relatively heavy, it is inconvenient to install and disassemble, and all the counterweight blocks are concentrated in the middle position of the counterweight frame, resulting in uneven force on the counterweight frame and deformation. Utility Model Content

[0004] The purpose of the utility model is to provide a counterweight structure for a heavy-duty hoist to solve the problems raised in the background technology.

[0005] The above-mentioned purpose of the utility model is achieved through the following technical solutions: a counterweight structure of a heavy-duty hoist, comprising a counterweight frame and a counterweight block, the counterweight frame comprising an upper crossbeam and a lower crossbeam distributed up and down and a plurality of columns vertically arranged between the upper crossbeam and the lower crossbeam, the columns divide the counterweight frame into a plurality of counterweight areas, the plurality of counterweight areas are spaced apart along the width direction of the counterweight frame, and symmetrically distributed in the width direction, a spacing area is formed between two adjacent counterweight areas, the counterweight block is arranged in the counterweight area, and a fixing component for fixing the counterweight block is arranged in the counterweight area.

[0006] Preferably, a fixing groove is provided on one side of the column facing the counterweight area, and two ends of the counterweight block are respectively inserted into the corresponding fixing grooves.

[0007] Preferably, an opening is provided at the upper end of the column, the opening is communicated with the fixing groove, and the counterweight block is installed in the fixing groove through the opening.

[0008] Preferably, an elastic support component is provided on the inner side wall of the fixing groove, and the elastic support components are linearly distributed up and down, and each layer of the counterweight blocks is clamped between the front and rear groups of the elastic support components.

[0009] Preferably, the elastic support assembly includes an elastic support sheet and an elastic cushion block. The upper end of the elastic support sheet is fixed on the inner side wall of the fixed groove, and the elastic cushion block is arranged at the lower end of the elastic support sheet and located between the elastic support sheet and the inner side wall of the fixed groove.

[0010] Preferably, the elastic support sheet includes an upper sheet body and a lower sheet body. The upper sheet body is inclined downward, and the lower sheet body is vertically connected to the lower end of the upper sheet body, and a gap for accommodating the elastic cushion block is formed between the lower sheet body and the inner side wall of the fixed groove.

[0011] Preferably, a retaining piece is arranged at the opening, and the retaining piece is fixed on the column.

[0014] Advantages of the present utility model:

[0015] 1. By arranging a plurality of columns between the upper cross beam and the lower cross beam, the counterweight frame is divided into a plurality of counterweight areas. This structural design greatly enhances the overall rigidity and stability of the counterweight frame, enabling it to resist greater overturning moments during heavy lifting operations and ensuring the safe operation of the equipment.

[0016] 2. The counterweight areas are spaced and symmetrically distributed along the width direction of the counterweight frame. This layout not only achieves uniform distribution of the counterweight but also effectively reduces the roll moment caused by uneven counterweight through symmetric design, further improving the stability of the equipment.

[0017] 3. A fixing assembly is arranged in each counterweight area to fix the counterweight blocks. Such a design allows for flexible adjustment of the number and position of the counterweight blocks in each counterweight area according to actual needs, thereby achieving precise control of the counterweight and meeting the requirements under different working conditions.

Detailed implementation mode

[0022] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This specific embodiment is only an explanation of the present utility model, and it is not a limitation of the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present utility model, it is protected by the patent law.

[0024] Embodiment: As Figure 1 and Figure 2 shown, a counterweight structure of a heavy hoist includes a counterweight frame 1 and a counterweight block 2. The counterweight frame 1 includes an upper cross beam 101 and a lower cross beam 102 distributed up and down, and a plurality of columns 103 vertically arranged between the upper cross beam 101 and the lower cross beam 102.

[0025] Guide wheels 3 are arranged at the four corners of the counterweight frame 1, and the four guide wheels 3 are respectively installed at both ends of the upper cross beam 101 and the lower cross beam 102.

[0026] The columns 103 divide the counterweight frame 1 into a plurality of counterweight areas 104. The plurality of counterweight areas 104 are spaced apart along the width direction of the counterweight frame 1 and are symmetrically distributed in the width direction. An interval area 105 is formed between two adjacent counterweight areas 104, and the counterweight block 2 is arranged in the counterweight area 104.

[0027] In this embodiment, the number of columns 103 is four. The four columns 103 divide the counterweight frame 1 into two counterweight areas 104 and an interval area 105. The two counterweight areas 104 are located on the left and right sides of the interval area 105.

[0028] A fixing groove 106 is arranged on one side of the column 103 facing the counterweight area 104, and both ends of the counterweight block 2 are respectively inserted into the corresponding fixing grooves 106.

[0029] An opening 107 is provided at the upper end of the column 103. The opening 107 communicates with the fixing groove 106, and the counterweight block 2 is loaded into the fixing groove 106 through the opening 107. A retaining piece 5 is provided at the opening 107, and the retaining piece 5 is fixed to the column 103 by bolts.

[0030] A fixing assembly 4 for fixing the counterweight block 2 is provided in the counterweight area 104. The fixing assembly 4 includes a threaded hole 401 and a tightening screw 402. The threaded holes 401 are linearly distributed up and down along the column 103. The tightening screw 402 is screwed into the threaded hole 401 and one end of the tightening screw 402 abuts against the counterweight block 2 to prevent the counterweight block 2 from moving in the length direction (i.e., the width direction of the counterweight frame 1).

[0031] As Figure 3 shown, the width of the fixing groove 106 is greater than the width of the counterweight block 2. Elastic support assemblies 6 are provided on the inner side wall of the fixing groove 106 and are linearly distributed up and down. Each layer of the counterweight block 2 is clamped between two sets of front and rear elastic support assemblies 6.

[0032] The elastic support assembly 6 includes an elastic support piece 601 and an elastic cushion block 602. The upper end of the elastic support piece 601 is fixed to the inner side wall of the fixing groove 106. The elastic cushion block 602 is arranged at the lower end of the elastic support piece 601 and is located between the elastic support piece 601 and the inner side wall of the fixing groove 106. The elastic support piece 601 can be a spring piece, and the elastic cushion block 602 is made of an elastic rubber block.

[0033] In the width direction of the counterweight block 2, since there is always a gap between the counterweight block 2 and the fixing groove 106, the counterweight block 2 is likely to vibrate and generate noise during the lifting and lowering process. Therefore, in this embodiment, two sets of elastic support assemblies 6 are provided in the fixing groove 106 to clamp the counterweight block 2 in the width direction, and the elastic cushion block 602 is used to reduce the vibration of the counterweight block 2, thereby reducing the noise.

[0034] In order to facilitate loading the counterweight block 2 into the fixing groove 106 from top to bottom, the elastic support piece 601 includes an upper piece body 6011 and a lower piece body 6012. The upper piece body 6011 is arranged to incline downward. The lower piece body 6012 is vertically connected to the lower end of the upper piece body 6011, and a gap for accommodating the elastic cushion block 602 is formed between the lower piece body 6012 and the inner side wall of the fixing groove 106. When loading the counterweight block 2, the inclined upper piece body 6011 guides the counterweight block 2 so that the counterweight block 2 can be smoothly loaded on one side of the lower piece body 6012 and is clamped by two sets of elastic support assemblies 6.
