[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0025] In the existing technologies, reciprocating elevators have many parts, are complicated to install, and take a long time, which affects the timely use by customers. Therefore, there is a need for a reciprocating elevator that is easier to assemble.

[0026] To address the problems existing in the relevant prior art, this utility model proposes a reciprocating hoist for freight storage. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0027] Please see Figures 1 to 6This utility model proposes a reciprocating hoist for freight storage, including an outer frame 1, a car 2, and a drive mechanism 3. The car 2 is located inside the outer frame 1. Driven by the drive mechanism 3, the car 2 is raised or lowered inside the outer frame 1 to place goods. The drive mechanism 3 then raises or lowers the car 2, thereby lifting the goods. The drive mechanism 3 includes a motor 301, a drive shaft 302, a counterweight box 303, and a chain 304 connecting the car 2 and the counterweight box 303. A top plate 4 is provided on the top of the outer frame 1. The motor 301 and the drive shaft 302 are fixed to the upper part of the top plate 4. The motor 301 drives the drive shaft 302 to rotate. Gears are provided on the drive shaft 302. Each of the four corners of the car 2 is equipped with a chain 304 connected to a counterweight box 303, and each chain 304 meshes with a gear on the drive shaft 302. The counterweight box and the car are both located inside the outer frame 1. The chains at the four corners of the car 2 connected to the counterweight box mesh with the gears on the drive shaft. On the one hand, the drive shaft 302 is rotated by the motor 301 to achieve the purpose of raising or lowering the car 2. On the other hand, it ensures that the force is evenly distributed at the four corners of the car 2 and prevents it from tilting to one side. The outer frame 1 is also equipped with a feed inlet and a discharge outlet on the side. The feed inlet and discharge outlet are equipped with protective doors 5. When feeding or discharging is required, the protective doors 5 are opened. When the car is rising or falling, the protective doors are kept closed.

[0028] The outer frame 1 is composed of multiple support modules stacked together. Each support module includes four columns 101 and a protective net 102. Adjacent columns 101 are connected by the protective net 102. At the same time, connecting rods (not shown in the figure) are added to improve the rigidity of the support module. The columns 101 and the protective net 102 of the multiple support modules form a "U"-shaped channel. Horizontal partitions 103 are provided inside the channel to divide the channel into a car channel and a counterweight box channel. The car is located in the car channel and the counterweight box is located in the counterweight box channel. Car guide rails 104 are provided on opposite sides in the car channel, and counterweight box guide rails 105 are provided in the counterweight box channel. Each support module is stacked vertically and fixedly connected to the corresponding column 101. At the same time, the car guide rails 104 and the counterweight box guide rails 105 are also connected to each other. Specifically, they can be fixedly connected by angle steel and bolts, or they can be reinforced by welding to prevent the bolts from loosening due to vibration during movement.

[0029] A buffer device is provided at the four corners of the upper part of the car 2 where it connects to the chain 304. Specifically, it includes a connecting rod 6 and a spring 7. The connecting rod 6 is fixedly connected to the car 2, and the spring 7 is fitted on the connecting rod 6. The chain 304 is connected to the connecting rod 6. When the chain 304 is connected to the car 2, the spring is in a compressed state. At the same time, when the car is lifted under the drive of the motor, the spring can effectively prevent the chain from breaking due to instantaneous start.

[0030] Both the upper and lower parts of the car 2 are equipped with buffer blocks 8, and the upper and lower parts of the two opposite sides of the car 2 are equipped with car guide shoes 9, which correspond to the car guide rails 104. Safety clamps 10 are located on the sides of the car 2, tension wheels 11 are located on the top plate 4, and speed limiting wheels 12 are located at the bottom of the outer frame 1. Safety ropes 13 are wrapped around the tension wheels 11 and speed limiting wheels 12, and the safety ropes 13 are connected to the safety clamps 10. The buffer blocks 8 have a buffering effect, which can effectively improve the overall safety performance. At the same time, the safety clamps 10 drive the speed limiting wheels 12 to rotate through the safety ropes. When the speed limiting wheels rotate beyond the rated speed, it indicates that there is a risk. The speed limiting wheels can lock in an emergency, causing the safety clamps to lock. The safety clamps cooperate with the car guide rails to lock and decelerate, ensuring safety.

[0031] The counterweight box 303 has a secondary shoe 14 on its side that cooperates with the counterweight box guide rail 105. The secondary shoe 14 cooperates with the counterweight box guide rail to ensure that the counterweight box will not sway horizontally during the up and down movement.

[0032] Safety light curtains 15 are installed on the side of the car 2 corresponding to the inlet and outlet. The safety light curtains 15 work in conjunction with the protective door 5. When an object is stuck in the position of the safety light curtain 15, the protective door 5 will not close when the power is off. Only when the safety light curtain can transmit and receive signals normally, that is, when there is no object on the surface of the inlet or outlet, will the protective door 5 open normally. An electric push rod 16 is installed at the bottom of the car 2. The horizontal partition 103 is equipped with a limit block 17 corresponding to the inlet and outlet, which works in conjunction with the electric push rod 16. When the car is at the inlet or outlet, electric push rods are installed on both sides of the lower part of the car. The electric push rod 16 extends out and works in conjunction with the limit block. In this way, the extended part of the electric push rod 16 rests on the limit block 17, which increases the force and also prevents the car from suddenly running due to someone accidentally touching the control system, which greatly improves safety.

[0033] A ladder 18 is provided on the outer side of the outer frame 1, and a guardrail 19 is provided on the upper side of the top plate 4. The drive mechanism needs to be inspected and maintained regularly. The ladder 18 and guardrail 19 can facilitate the inspection and maintenance while ensuring the safety of the inspection.

[0034] By setting the car as a fixed structure, the outer frame is formed by stacking and connecting multiple support modules. The structure is relatively simple and can be quickly assembled and disassembled. The drive mechanism mainly includes a motor and a counterweight box. On-site, multiple support modules are simply stacked to form the outer frame, and then the car and drive mechanism are installed accordingly. Finally, other accessories are installed before use. This can greatly improve assembly efficiency, make it easier for customers to use, and ensure sufficient safety.

[0035] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
