Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a lifting assembly. Background Technology

[0002] The working process of the casting station is as follows: The carbon block conveyor delivers qualified new anode carbon blocks to the front end of the roller conveyor of the casting line. Under the control of the electrical system, the roller conveyor accurately delivers the anode carbon blocks to the mold closing station. At the same time, the overhead conveyor delivers qualified guide rod assemblies to the mold closing station. After the guide rod assemblies and anode carbon blocks arrive at the mold closing station, the positioning mechanism positions the guide rod assemblies and anode carbon blocks respectively. After positioning, the lifting device lifts the anode carbon blocks so that the steel claws accurately insert into the anode carbon blocks, completing the mold closing action. After the mold closing is completed, the roller conveyor pushes the mold-closed guide rod assembly to the casting waiting station. The roller conveyor transports the guide rod assembly from the casting station to the casting station. The positioning mechanism at the casting station positions the guide rods. After positioning, a manual casting trolley accurately pours molten iron from the ladle into the carbon bowl to complete the casting of the guide rod assembly and anode carbon blocks. After casting, the positioning mechanism opens, and the roller conveyor pushes the cast guide rod assembly to the cooling station. After cooling, it is pushed to the online casting station. Once the guide rod assembly reaches the online casting station, the lifting mechanism lowers, causing the overhead conveyor bell to be stressed. After lowering to its final position, the overhead conveyor carries away the finished anode, and then all mechanisms reset to begin the next work cycle. Under the control of mechatronics, the casting station completes the processes of mold closing, casting, cooling, online casting, and waste block disposal for the anode and guide rod assembly.

[0003] The existing guide rod assembly and anode carbon block need to be positioned and then inserted relatively close together to complete the meshing operation. However, if the lifting of both is unstable, the position may be inaccurate, leading to the failure of the guide rod assembly and anode carbon block to close the mold. Utility Model Content

[0004] The purpose of this utility model is to provide a lifting component to solve the technical problem of unstable lifting in the prior art.

[0005] To solve the above problems, the lifting assembly involved in this utility model adopts the following technical solution:

[0006] This utility model provides a lifting assembly, including a main frame, a mounting frame slidably mounted on the main frame, a drive sprocket, a driven sprocket, a chain, and a transmission mechanism. The transmission mechanism is mounted on the main frame, and the mounting frame is equipped with a lifting joint assembly whose length is adjustable. The drive sprocket and the driven sprocket are respectively located on the upper and lower sides of the lifting joint assembly. The drive sprocket and the driven sprocket are rotatably engaged with the main frame. The chain passes through the drive sprocket and the driven sprocket in sequence, and its two ends are respectively connected to the upper and lower ends of the lifting joint assembly. The transmission mechanism is in transmission engagement with the drive sprocket, and the transmission mechanism works to drive the mounting frame to move back and forth along the height direction of the main frame via the chain.

[0007] Preferably, the lifting joint assembly includes a lead screw and two joint bodies located at both ends of the lead screw. One end of each joint body is connected to one end of a chain, and the other end of each joint body is screwed to the lead screw. The lead screw passes through a mounting frame, and two first nuts located on the upper and lower sides of the mounting frame are screwed onto the lead screw. The position of the lead screw on the mounting frame is constrained by adjusting the position of the two first nuts on the lead screw. Two second nuts are screwed onto the lead screw, which abut against the two joint bodies. The length of the lifting joint assembly is adjusted by adjusting the position of the second nuts on the same side and the joint bodies on the lead screw.

U-shaped guide grooves extending along the height direction are provided on the opposite sides of the two uprights. A mounting frame is disposed between the two uprights. Sliding structures are respectively provided on the sides of the mounting frame corresponding to the two uprights. The sliding structures are matched and disposed in the U-shaped guide grooves of the corresponding uprights, so that the mounting frame can move up and down along the main frame under the limitation of the sliding structures and the U-shaped guide grooves.

[0009] Preferably, the sliding structure is configured as a composite roller bearing, and at least two composite roller bearings are spaced apart along the length of the mounting frame on either side corresponding to the two uprights.

[0010] Preferably, the transmission mechanism is configured as a geared motor, which is connected to the drive sprocket. The geared motor drives the drive sprocket to rotate.

The chain passes around the drive sprocket and driven sprocket in sequence, and its two ends are connected to the upper and lower ends of the lifting joint assembly. The transmission mechanism drives the drive sprocket, and operates to move the mounting frame back and forth along the height direction of the main frame via the chain. This device can change its length according to actual needs.

[0020] To make the technical objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] This utility model provides a lifting assembly, including a main frame 201, a mounting bracket 202 slidably disposed on the main frame 201, a drive sprocket 203, a driven sprocket 204, a chain 205, and a transmission mechanism 206, wherein:

[0022] The main frame 201 consists of at least two parallel and spaced uprights and a crossbeam located between the two uprights and connecting the two uprights. U-shaped guide grooves extending along the height direction are provided on the opposite sides of the two uprights. The transmission mechanism 206 is installed on the crossbeam.

[0023] The mounting frame 202 is located between two uprights. Sliding structures 207 are provided on the sides of the mounting frame 202 corresponding to the two uprights, and at least two sliding structures 207 are provided at intervals on any side. Each sliding structure 207 is slidably matched in the U-shaped guide groove of its corresponding upright, so that the mounting frame 202 can move up and down along the main frame 201 under the limitation of the sliding structure 207 and the U-shaped guide groove.

[0024] The sliding structure 207 is configured as a composite roller bearing. The transmission mechanism 206 is configured as a geared motor, the working shaft of which is connected to the drive sprocket 203. The geared motor drives the drive sprocket 203 to rotate when it operates.

[0025] The mounting frame 202 is equipped with an adjustable lifting joint assembly 208. A drive sprocket 203 and a driven sprocket 204 are respectively positioned on the upper and lower sides of the lifting joint assembly 208. The driven sprocket 204 is rotatably mounted on a support beam of the main frame 201 (the support beam is a beam located between and connected to the two uprights, used to improve the stability of the main frame 201 and for mounting accessories). A chain 205 passes sequentially around the drive sprocket 203 and the driven sprocket 204, and its two ends are respectively connected to the upper and lower ends of the lifting joint assembly 208. 205 is used to convert the rotational motion of the drive sprocket 203 into the linear motion of the hoisting frame. Its working principle is that when the transmission mechanism 206 (reduction motor) is working, it drives the drive sprocket 203 to rotate. The rotation of the drive sprocket 203 drives the driven sprocket 204 to rotate through the chain 205. At the same time, the movement of the chain 205 is connected to the hoisting frame through the hoisting joint assembly 208, which drives the mounting frame 202 to move up and down. Under the limitation of the sliding structure 207 and the U-shaped groove, the hoisting frame moves back and forth along the height direction of the main frame 201.

[0026] The lifting joint assembly 208 includes a lead screw 2081 slidably mounted on the lifting frame and two joint bodies 2082 respectively located at both ends of the lead screw 2081. Specifically, the lead screw 2081 passes through the lifting frame, and two first nuts 2083 located on the upper and lower sides of the lifting frame and two second nuts 2084 respectively used to abut against the two joint bodies 2082 are screwed onto the lead screw 2081. One end of the two joint bodies 2082 is respectively connected to the two ends of the chain 205, and the other end is screwed to the lead screw 2081. The joint bodies 2082 serve to connect the chain 205 and the lead screw 2081, and transmit the tension of the chain 205 to the lead screw 2081, thereby realizing the up and down movement of the lifting frame. By adjusting the positions of the two first nuts 2083 on the lead screw 2081, the user can constrain the position of the lead screw 2081 on the lifting frame. Their function is to fix the vertical position of the lead screw 2081 on the lifting frame, preventing it from swaying or shifting during lifting. By adjusting the positions of the second nut 2084 on the same side and the connector body 2082 on the lead screw 2081, the user can adjust the length of the lifting connector assembly 208. Specifically, when adjusting the tension of the chain 205 or adapting to different lifting heights, the user changes the overall length of the lifting connector assembly 208 by rotating the relative position of the connector body 2082 and the lead screw 2081, and by tightening the second nut 2084 to abut against the connector body 2082, thus constraining the movement of the connector body 2082.

[0027] Furthermore, a transmission assembly consisting of a driving sprocket, a driven sprocket, a chain, and a lifting joint assembly is defined as a transmission assembly. This device has at least two transmission assemblies, which are located on both sides of the geared motor. The geared motor is connected to the driving sprocket located on both sides of the motor.

[0028] Finally, it should be noted that the above embodiments are only for illustration and not for limiting the technical solutions of this utility model. Any equivalent substitutions and modifications or partial substitutions that do not depart from the spirit and scope of this utility model should be covered within the scope of protection of the claims of this utility model.
