Abstract
Description
Technical Field
[0001] This utility model relates to the field of linear motor technology, specifically a linear motor for carrying heavy loads. Background Technology
[0002] Linear motors are currently used in various fields. When linear motors are used in cargo conveying equipment, they can only transport goods and cannot lift heavy objects. This requires manual bending over to move the goods, which leads to high labor intensity for workers.
[0003] In the prior art, the authorized patent with publication number CN221876496U discloses a linear motor for carrying heavy objects. The linear motor includes a linear motor body and a movable slide. The linear motor body drives the movable slide to move. A support plate is provided on the upper side of the movable slide, and a lifting device is provided on the periphery or upper surface of the movable slide. The lifting device drives the support plate to rise and fall. By using the support plate to carry the heavy object, and the linear motor body driving the movable slide and support plate to move to a designated position, when the support plate reaches the designated position, the lifting device drives the support plate to rise, thereby moving the goods upwards. This allows the goods to be moved to a height that does not require manual bending, thus reducing the labor intensity of moving heavy objects.
[0004] However, the above technical solution still has the following shortcomings in practical use: the device lacks a clamping mechanism to secure the goods, making it easy for the goods to fall off the support plate during movement or lifting. To address this, we propose a linear motor for carrying heavy loads. Utility Model Content
[0005] The purpose of this invention is to provide a linear motor for carrying heavy loads, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a linear motor for carrying heavy loads, comprising:
[0007] A linear motor body is provided, on which a ball screw is mounted. A slide rod is fixedly mounted on the linear motor body, and a movable seat is mounted on the ball screw. The movable seat is slidably connected to the slide rod. Two hydraulic rods are fixedly mounted on the front and rear side walls of the movable seat. A base is fixedly mounted on the top of each hydraulic rod. A support column is fixedly welded to the top wall of the base. A bearing plate is fixedly welded to the top of each support column. A mounting ring is provided on the support column. Two L-shaped mounting brackets are fixedly welded to the mounting ring. A screw is threadedly connected to each L-shaped mounting bracket through a threaded hole. A clamping plate is rotatably mounted on the inner end of each screw. A guide rod is fixedly welded to the clamping plate and slidably connected to the L-shaped mounting bracket.
[0008] Preferably, the mounting ring is rotatably mounted on the support column via a bearing, and a limiting ring is fixedly welded to the bottom wall of the mounting ring, the limiting ring being sleeved on the support column.
[0009] Preferably, a fixed seat is fixedly welded to the front top wall of the base, a stud is threadedly connected to the fixed seat, an arc-shaped locking block is rotatably installed at the rear end of the stud, a guide post is fixedly welded to the arc-shaped locking block, and the guide post is slidably connected to the fixed seat.
[0010] Preferably, a first handwheel is fixedly installed at the outer end of the screw.
[0011] Preferably, a second handwheel is fixedly installed at the front end of the stud.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] In use, after the goods are placed on the support plate, the screw can be rotated forward by turning the two first handwheels in sequence. This causes the screw to clamp the clamping plate onto the goods on the support plate under the guidance of the guide rod, ensuring the stability of the goods during transportation and lifting, and preventing the goods from falling off the support plate and causing damage. The clamping plates can be adjusted in position by rotating the mounting ring on the support column, making it convenient for the clamping plates to clamp the goods in the appropriate position. Turning the second handwheel forward causes the stud to rotate forward, causing the stud to move the arc-shaped locking block backward and press it against the limit ring, thereby limiting and fixing the mounting ring and ensuring the stability of the clamping plate.
