Description

Technical Field

[0001] The utility model belongs to the technical field of lifting and conveying devices, and in particular relates to a single-side frame hoist. Background Art

[0002] Lifting and conveying devices are widely used in production, warehousing, logistics and other fields. With the rapid development of intelligent, intensive and unmanned factory management, there are new requirements for their quantity, performance and cost. The traditional lifting mechanism is mainly composed of the main frame, lifting machinery, loading device, connecting rope end, etc.

[0003] Since the main frame needs to be made into two, the hoist occupies a large area. Also, because there are frames on both sides, the power attenuation of the motor installed on one side frame is large when transmitting power to the other side frame. Therefore, a larger power motor is needed to provide sufficient lifting power. However, a large power motor generally requires a larger volume for heat dissipation, which makes it impossible to install the motor in the main frame, further increasing the floor space. Therefore, it is urgent to design a single-side frame hoist to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a single-side frame hoist to solve the problems existing in the above-mentioned background technology.

[0026] The present invention provides a unilateral frame elevator as shown in Figures 1-5 and includes:

[0027] The frame body 100 includes a support frame 101, one side of the support frame 101 is provided with two mutually parallel guide rails 102 and the other side is provided with two mutually parallel guide rails 2 104, the guide rail 1 102 is slidably connected with a guide shoe 103, and the guide rail 2 104 is slidably connected with a guide shoe 2 105;

[0028] The counterweight mechanism 200 includes a counterweight frame 201, a counterweight block 202 disposed in the counterweight frame 201, and a clamping rod 203 for limiting the counterweight block 202. Both sides of the counterweight frame 201 are fixedly connected to the guide shoe 2 105 slidably connected to the guide rail 2 104, so that the counterweight frame 201 can move along the guide rail 2 104 together with the guide shoe 2 105. A plurality of counterweight blocks 202 are stacked and arranged inside the counterweight frame 201. The number of counterweight blocks 202 can be adjusted according to actual needs. The clamping rod 203 runs through the counterweight frame 201 and the counterweight block 202, and is fixedly connected to the counterweight frame 201 by bolts, so as to prevent the counterweight block 202 from falling off.

[0029] The stage mechanism 300 is arranged on one side of the frame body 100, one side of the stage mechanism 300 is fixedly connected to the guide shoe 103 slidably connected to the guide rail 102, and a connecting block 305 is fixed on one side of the stage mechanism 300;

[0030] The power mechanism 400 includes a lifting motor 401, a transmission shaft 402 and a chain 403. A sprocket 405 is fixed on the transmission shaft 402. The chain 403 is connected to the transmission shaft 402 through the sprocket 405, and the two ends of the chain 403 are respectively fixedly connected to the counterweight frame 201 and the connecting block 305. The lifting motor 401 is connected to the transmission shaft 402 through the sprocket 2 406 and the chain 2 407.

[0031] In addition, the platform mechanism 300 includes a cargo platform 301 and a guardrail 302 fixed on the top of the cargo platform 301, a mounting plate 303 and a conveying unit 304. The mounting plate 303 is fixed to both sides of the conveying unit 304 by bolts to facilitate the installation of the conveying unit 304. The guardrail 302 is arranged on the outer side of the mounting plate 303 to prevent the cargo from falling off.

[0032] Specifically, the conveying unit 304 includes a conveying motor 3041, a transmission shaft 3042, and a driving wheel 3045 and a driven wheel 3046 arranged at both ends of the mounting plate 303. The two ends of the transmission shaft 3042 are rotatably connected to the mounting plate 303 through bearings, and the two ends of the transmission shaft 3042 pass through the mounting plate 303 and are fixedly connected to the driving wheel 3045. When the transmission shaft 3042 rotates, it can drive the driving wheel 3045 to rotate. A synchronous wheel is fixed on the transmission shaft 3042. 3043, the conveying motor 3041 is connected to the synchronous wheel 3043 through the synchronous belt 3044, the conveying motor 3041 can drive the transmission shaft 2 3042 to rotate, the conveying belt 3048 is tensionedly connected between the driving wheel 3045 and the driven wheel 3046, the rotation of the driving wheel 3045 can drive the conveying belt 3048 to move, so as to facilitate the transportation of goods, and a plurality of supporting wheels 3047 are arranged between the driving wheel 3045 and the driven wheel 3046 to facilitate better support of the goods.

[0033] It is worth mentioning that there are two transmission shafts 402, which are respectively arranged at the top and bottom of the frame body 100, so that the chain 403 connecting the two transmission shafts 402 is arranged in the vertical direction. When the chain 403 moves, it can drive the cargo platform 301 to move in the vertical direction. Bearing seats 404 are provided at both ends of the transmission shaft 402 to facilitate the installation of the transmission shaft 402.

[0034] Specifically, there are four chains 403, and two of them are connected in groups to form a motion circuit through the counterweight frame 201 and the connecting block 305, so that the gravity of the counterweight mechanism 200 can be used as the lifting force of the platform mechanism 300, thereby greatly reducing the power of the lifting motor 401.

[0035] It should be noted that both the counterweight frame 201 and the counterweight block 202 are provided with through holes matching the diameter of the clamping rod 203 , so that the clamping rod 203 can pass through the counterweight frame 201 and the counterweight block 202 , thereby ensuring stable installation of the counterweight block 202 .

[0036] Specifically, lifting rings 204 are fixed on both sides of the top of the counterweight frame 201 to facilitate lifting and moving the counterweight frame 201.

[0037] Working principle: When the unilateral frame hoist is in use, first place the goods on the loading platform 301, and then start the lifting motor 401. The lifting motor 401 drives the first transmission shaft 402 located at the bottom of the frame body 100 to rotate through the second chain 407. The first transmission shaft 402 drives the first chain 403 to move. At this time, the counterweight mechanism 200 at one end of the first chain 403 descends and the loading platform 301 and the goods at the other end rise. When the goods rise to the specified height, start the conveying motor 3041. The conveying motor 3041 drives the second transmission shaft 3042 to rotate through the second chain 407, and then drives the conveyor belt 3048 to move through the driving wheel 3045 and the driven wheel 3046, and conveys the goods to the specified position. The unilateral frame hoist is advanced in design, compact in structure and convenient to use. The counterweight frame 201 and the loading platform 301 are connected by the first chain 403. Equivalently, the counterweight mechanism 200 provides the lifting power equal to the weight for the lifting of the loading platform mechanism 300, so that the power of the lifting motor 401 can be greatly reduced, thereby reducing the power consumption of the lifting motor 401, achieving cost reduction and efficiency improvement. After the power is reduced, the volume of the lifting motor 401 will also be much smaller. Therefore, the lifting motor 401 can be placed inside the frame body 100 to further reduce the floor space occupied by the unilateral frame hoist.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
