Description

Technical Field

[0001] This utility model relates to a rack and pinion mechanism, specifically a rack and pinion mechanism for a lift with multiple connection methods, belonging to the field of lift rack and pinion technology. Background Technology

[0002] The rack and pinion drive structure commonly used in lifting platforms (such as construction hoists, freight elevators, stage hoists, etc.) is a reliable and efficient vertical lifting solution. Its core is to achieve power transmission and positioning through the meshing of gears and racks.

[0003] However, when the lifting platform is in use, there are usually multiple grooves on one side of the rack lifting rod. During the movement, the force on one side of the lifting rod is greater, which can easily lead to uneven load distribution on both sides, resulting in local wear of the rack. In addition, the rack and the lifting rod are generally set as one piece, making it inconvenient to replace the worn rack, thus reducing the efficiency of the rack. Utility Model Content

[0004] The purpose of this utility model is to provide a rack and pinion mechanism for a lift with multiple connection methods to solve the above problems. Two gears drive two racks to move the sliding mechanism, so that the load on both sides of the sliding mechanism is evenly distributed, which helps to prevent excessive force on one side from causing local wear of the rack or gear.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a rack and pinion mechanism for a multi-mode connected elevator, comprising a base plate, a drive mechanism fixedly mounted on the base plate, the drive mechanism comprising a protective cover and a rotating rod, a protective cover fixedly connected to the top of the base plate, a rotating rod rotatably mounted on the protective cover, a gear fixedly connected to the rotating rod, a rack meshing with the gear, a locking plate fixedly connected to the rack, a sliding mechanism engaging on the locking plate, a fixing block fixedly connected to the protective cover, and an insert block engaging between two fixing blocks.

[0006] Preferably, the two base plates, protective covers, and fixing blocks abut against each other, and the rack is located between the two protective covers.

[0007] Preferably, the drive mechanism further includes a slot, and the fixing block is provided with a slot, which is arranged in a T-shape.

[0008] Preferably, the slot portion is fitted with a plug block, and the height of the plug block and the slot is less than the height of the fixing block.

[0009] Preferably, the sliding mechanism includes a support and a lifting rod. The lifting rod is fixedly installed on the rack, and the two ends of the lifting rod are respectively fixedly connected to the support and the locking block. The base is fixedly installed on the locking block.

[0010] Preferably, the two racks are symmetrically arranged on the side wall of the lifting rod, and the protective cover is arranged with an arc-shaped structure near the top of the rack.

[0011] Preferably, the lifting rod is slidably connected to the base plate and the protective cover, and the lifting rod is located in the middle of the two base plates and the protective cover.

[0012] Preferably, the sliding mechanism includes a slot, and the lifting rod is provided with a slot near the rack, and a card is engaged in the slot.

[0013] Preferably, both the card plate and the card slot are arranged in an isosceles trapezoidal structure, and the length of the rack is greater than the length of the card plate.

[0014] Preferably, the diameters of the support and the chassis are both larger than the diameter of the lifting rod, and the part where the locking block engages with the chassis is designed with an arc-shaped structure.

[0015] The beneficial effects of this utility model are as follows: Two base plates and protective covers are symmetrically installed on both sides of the sliding mechanism. The base plates are fixed to the equipment with fixing bolts, so that the two protective covers are in a state of mutual contact. Since there are fixing blocks installed on the protective covers, the two ends of the insert blocks are engaged and installed into the inside of the fixing blocks, so that the two protective covers can be connected. Then, by rotating the rotating rods installed on both protective covers with tools, the gears fixed at their ends can drive the racks to move. The two racks drive the sliding mechanism to move, so that the load on both sides of the sliding mechanism can be evenly distributed, making the movement of the elevator more stable. At the same time, it also prevents the racks and gears from being locally worn due to excessive force on one side of the sliding mechanism. The racks are connected to the sliding mechanism through the clamping plate, so that when they are severely worn, the two racks on the sliding mechanism can be replaced, which is beneficial to improving the performance of the sliding mechanism.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 As shown, a rack and pinion mechanism for a multi-connected elevator includes a base plate 1. A drive mechanism 2 is fixedly mounted on the base plate 1. The drive mechanism 2 includes a protective cover 201 and a rotating rod 202. The protective cover 201 is fixedly connected to the top of the base plate 1. The rotating rod 202 is rotatably mounted on the protective cover 201. A gear 206 is fixedly connected to the rotating rod 202. A rack 3 meshes with the gear 206. The rack 3 is located between two protective covers 201. By rotating the rotating rod 202 with a tool, it drives the gear 206 at its end to rotate within the protective cover 201. The gear 206 drives the rack 3 to slide, causing the rack 3 to... The sliding mechanism 4 is displaced, thereby making the force on both sides of the sliding mechanism 4 more even; a clamping plate 5 is fixedly connected to the rack 3, and the sliding mechanism 4 is engaged on the clamping plate 5. The rack 3 is installed on the sliding mechanism 4 by fixing bolts, and can be replaced when the rack 3 is severely worn; a fixing block 203 is fixedly connected to the protective cover 201, and a slot 205 is provided on the fixing block 203. An insert block 204 is engaged in the slot 205, and the insert block 204 is engaged with the fixing block 203, which can limit the two fixing blocks 203, and can also connect the two protective covers 201 together.

[0026] As a technical optimization of this utility model, the sliding mechanism 4 includes a support 401 and a lifting rod 402. The lifting rod 402 is fixedly installed on the rack 3. Under the driving force of the gear 206, the rack 3 can drive the lifting rod 402 to move up and down. The two ends of the lifting rod 402 are respectively fixedly connected to the support 401 and the locking block 404. The base 403 is fixedly installed on the locking block 404. When the lifting rod 402 drives the locking block 404 and the base 403 to move upward, the base 403 can be engaged with the sliding mechanism 402. The bottom end of the base plate 1 contacts the base plate 1, thereby preventing the lifting rod 402 from continuing to slide. The lifting rod 402 is slidably connected to the base plate 1 and the protective cover 201. When the lifting rod 402 moves between the base plate 1 and the protective cover 201, it can drive the equipment fixed on the support 401 to move. The lifting rod 402 is provided with a slot 405 near the rack 3. A retaining plate 5 is engaged in the slot 405. The slot 405 limits the retaining plate 5, and its position can be quickly determined when the rack 3 is replaced.

[0027] In use, the operator first assembles the two base plates 1 and the protective cover 201 together, so that the base plates 1 and the protective cover 201 surround the lifting rod 402 in the middle. Then, the base plates 1 are fixed to the equipment with fixing bolts. At this time, the two protective covers 201 are in a state of mutual contact, thereby limiting the lifting rod 402. Since the side wall of the protective cover 201 is equipped with fixing blocks 203, the two ends of the insert block 204 are engaged and installed into the slot 205 provided in the fixing block 203. The slot 205 is T-shaped. By limiting the two fixing blocks 203 with the insert block 204, the two protective covers 201 can be fixed together. Then, the rotating rod 202 installed on both protective covers 201 is rotated with a tool. The rotating rod 202 drives the lifting rod 402 to move the lifting rod 402. The gear 206 fixed at the end rotates inside the protective cover 201. The gear 206 meshes with the rack 3 on the side near the protective cover 201. The gear 206 starts to rotate, which can drive the rack 3 to move. The two racks 3 are symmetrically installed on the side wall of the lifting rod 402. The movement of the racks 3 can drive the lifting rod 402 to move, which can make the load on both sides of the lifting rod 402 evenly distributed, thereby making the movement of the lifting machine more stable. At the same time, it also prevents the lifting rod 402 from being subjected to excessive force on one side, which would cause local wear of the racks 3. The retaining plate 5 fixed on the rack 3 engages with the retaining groove 405 provided in the lifting rod 402. The rack 3 and the retaining plate 5 are fixed on the lifting rod 402 by fixing bolts. When the rack 3 is severely worn, the two racks 3 on the lifting rod 402 can be replaced, which will help improve the efficiency of the sliding mechanism 4.
