[0001] This utility model belongs to the field of electric hoist technology, specifically, it relates to a fixing structure for the trolley of an electric hoist single and double beam crane. Background Technology
[0002] An electric hoist is a special lifting device consisting of an electric motor, a transmission mechanism, and a drum or sprocket. It is divided into two types: wire rope and chain. Electric hoists are installed on overhead cranes and gantry cranes. They are characterized by their small size, light weight, simple operation, and convenient use. They are mainly used in industrial and mining enterprises, warehouses, docks, and other places.
[0003] Electric hoists are installed on overhead cranes and gantry cranes to lift objects. Under long-term continuous operation, the guide rails used for the horizontal movement of the electric hoist will inevitably wear out. If they are not lubricated, the aging and damage of the guide rails will be accelerated, which will not be conducive to the movement of the electric hoist, and may even cause safety accidents during lifting operations.
[0004] In view of this, the present invention proposes a fixing structure for the trolley of an electric hoist single and double beam crane to solve the above problems. Utility Model Content
[0005] To address the issue that the guide rails used for lateral movement of electric hoists inevitably wear down during prolonged continuous operation, and that failure to lubricate them accelerates aging and damage, hindering the movement of the electric hoist, the basic concept of this utility model is as follows:
[0006] A fixing structure for a single / double girder crane trolley with an electric hoist includes an I-beam and an electric hoist. Symmetrically arranged sliding supports are slidably mounted on the I-beam. Each of the two sliding supports has a first infusion slot. Symmetrically arranged guide rails are provided at the bottom of the I-beam, with the first infusion slots located directly above the guide rails. Each of the two sliding supports has a second infusion slot, which is connected to the first infusion slot. A connecting rail is provided in the middle of the I-beam, with the second infusion slots symmetrically arranged on both sides of the connecting rail. A common mounting box is fixedly mounted on the top of the two sliding supports, and the bottom of the mounting box has symmetrically arranged... The installation box has an opening, and the inner wall of the opening is fixedly connected to an infusion tube. The infusion tube is connected to the first infusion tank. A partition is fixedly installed inside the installation box. A liquid storage chamber is provided between the bottom of the partition and the inner bottom of the installation box. A symmetrically arranged sealing seat is slidably installed on the inner bottom wall of the liquid storage chamber. The two sealing seats are respectively located directly above the two infusion tubes. A rectangular opening is opened in the middle of the partition, and a lifting frame is slidably installed on the inner wall of the rectangular opening. A symmetrically arranged guide rod is hinged to the bottom of the lifting frame. The bottom ends of the two guide rods are respectively hinged to the two sealing seats. A cylinder is fixedly installed on the top of the installation box. The piston rod of the cylinder is connected to the outer wall of the top of the lifting frame.
[0007] In a preferred embodiment of this utility model, symmetrically arranged sliding plates are fixedly connected to the outer walls on both sides of the two sliding supports, and the sliding plates are slidably connected to the inner wall of the guide rail.
[0008] In a preferred embodiment of this utility model, symmetrically arranged guide blocks are fixedly installed on the outer walls of the two sliding supports on opposite sides, and the guide blocks are slidably connected to the inner wall of the connecting track.
[0009] In a preferred embodiment of this utility model, a fixing plate is fixedly connected to the bottom outer wall of each of the two sliding supports, and the same mounting plate is fixedly connected to the bottom outer wall of the two fixing plates. The electric hoist is mounted on the bottom outer wall of the mounting plate.
[0010] In a preferred embodiment of this utility model, a mounting bracket is fixedly connected to the top outer wall of the mounting box, the cylinder is fixedly mounted on the mounting bracket, a through hole is opened in the middle of the top of the mounting box, and the cylinder piston rod is located inside the through hole.
[0011] In a preferred embodiment of this utility model, an installation hole is provided on one side of the installation box, and a liquid injection pipe is fixedly connected to the inner wall of the installation hole, and the liquid injection pipe is connected to the liquid storage chamber.
[0012] Compared with the prior art, the present invention has the following advantages:
[0013] In this invention, when the electric hoist is moving and the guide rail and connecting rail need lubrication, the cylinder is activated. The cylinder drives the lifting frame to move upward. The two sealing seats on the lifting frame change the tilt angle of the two guide rods. This change in the tilt angle of the two guide rods causes the two sealing seats to move relative to each other. After moving a certain distance, the lubricating oil in the storage chamber can enter the first infusion tank through the infusion pipe, allowing the lubricating oil to flow into the guide rail and lubricate it. Since the second infusion tank is connected to the first infusion tank, some lubricating oil will flow into the connecting rail through the second infusion tank, lubricating it as well. This delays the aging and damage of the guide rail and connecting rail, and facilitates the smooth movement of the electric hoist.

The following embodiments are used to illustrate this utility model.
[0023] like Figures 1 to 5 As shown
[0024] A fixed structure for a single / double girder crane trolley with an electric hoist includes an I-beam 1 and an electric hoist 2. Symmetrically arranged sliding supports 3 are slidably mounted on the I-beam 1. Each sliding support 3 has a first infusion slot 12. Symmetrically arranged guide rails 6 are provided at the bottom of the I-beam 1, with the first infusion slots 12 located directly above the guide rails 6. Symmetrically arranged sliding plates 7 are fixedly connected to the outer walls on both sides of each sliding support 3, and the sliding plates 7 are slidably connected to the inner walls of the guide rails 6. Each sliding support 3 has a second infusion slot 13, which communicates with the first infusion slot 12. A connecting rail 8 is provided in the middle of the I-beam 1. The liquid inlets 13 are symmetrically arranged on both sides of the connecting rail 8. Two sliding supports 3 have symmetrically arranged guide blocks 9 fixedly installed on their opposite outer walls, and the guide blocks 9 are slidably connected to the inner wall of the connecting rail 8. The tops of the two sliding supports 3 are fixedly installed with the same mounting box 10. The bottom of the mounting box 10 has symmetrically arranged openings, and each opening's inner wall is fixedly connected to an infusion tube 11. The infusion tube 11 communicates with the first infusion inlet 12. A partition 17 is fixedly installed inside the mounting box 10. A liquid storage chamber 18 is provided between the bottom of the partition 17 and the inner bottom of the mounting box 10. A symmetrically arranged sealing seat 21 is slidably installed on the inner bottom wall of the liquid storage chamber 18. The two sealing seats 21 are located at the two infusion inlets respectively. Above pipe 11, a rectangular opening is formed in the middle of partition 17, and a lifting frame 19 is slidably mounted on the inner wall of the rectangular opening. Symmetrically arranged guide rods 20 are hinged to the bottom of the lifting frame 19. The bottom ends of the two guide rods 20 are respectively hinged to two sealing seats 21. A cylinder 15 is fixedly mounted on the top of the mounting box 10. The piston rod of the cylinder 15 is connected to the outer wall of the top of the lifting frame 19. When the electric hoist 2 moves and lubrication of the guide rail 6 and connecting rail 8 is required, the cylinder 15 is activated, causing the lifting frame 19 to move upward. The two sealing seats 21 on the lifting frame 19 change the tilt angle of the two guide rods 20. When the tilt angle changes, it can drive the two sealing seats 21 to move relative to each other. After moving a certain distance, the lubricating oil in the liquid storage chamber 18 can enter the first liquid inlet 12 through the liquid inlet pipe 11, so that the lubricating oil can flow to the guide rail 6 through the first liquid inlet 12, so as to achieve the lubrication of the guide rail 6, and make the slide plate 7 move more smoothly in the guide rail 6. Since the second liquid inlet 13 is connected to the first liquid inlet 12, some lubricating oil will flow to the connecting rail 8 through the second liquid inlet 13, so as to achieve the lubrication of the connecting rail 8, and make the guide block 9 move more smoothly in the connecting rail 8.
[0025] In a specific embodiment, a fixing plate 4 is fixedly connected to the bottom outer wall of each of the two sliding supports 3, and the same mounting plate 5 is fixedly connected to the bottom outer wall of the two fixing plates 4. The electric hoist 2 is installed on the bottom outer wall of the mounting plate 5. The electric hoist 2 is installed on the I-beam 1 through the sliding supports 3, fixing plates 4, mounting plates 5, guide rails 6, sliding plates 7, connecting rails 8 and guide blocks 9, so that the sliding plates 7 slide on the inner wall of the guide rails 6 and the guide blocks 9 slide on the inner wall of the connecting rails 8. An installation hole is opened on one side of the mounting box 10, and an injection pipe 16 is fixedly connected to the inner wall of the installation hole. The injection pipe 16 is connected to the liquid storage chamber 18. The injection pipe 16 facilitates the injection of an appropriate amount of lubricating oil into the liquid storage chamber 18. An installation frame 14 is fixedly connected to the top outer wall of the mounting box 10, and a cylinder 15 is fixedly installed on the installation frame 14. A through hole is opened in the middle of the top of the mounting box 10, and the piston rod of the cylinder 15 is located inside the through hole.
[0026] The implementation principle of the fixing structure of the electric hoist single and double beam crane trolley in this embodiment is as follows:
[0027] In practical use, the electric hoist 2 is installed on the I-beam 1 via the sliding support 3, fixing plate 4, mounting plate 5, guide rail 6, sliding plate 7, connecting rail 8, and guide block 9. This allows the sliding plate 7 to slide on the inner wall of the guide rail 6 and the guide block 9 to slide on the inner wall of the connecting rail 8. A suitable amount of lubricating oil is injected into the storage chamber 18 through the injection pipe 16. When the electric hoist 2 moves and requires lubrication of the guide rail 6 and connecting rail 8, the cylinder 15 is activated. The cylinder 15 drives the lifting frame 19 upwards. The lifting frame 19, in conjunction with the two sealing seats 21, changes the tilt angle of the two guide rods 20. When the angle changes, it can drive the two sealing seats 21 to move relative to each other. After moving a certain distance, the lubricating oil in the liquid storage chamber 18 can enter the first liquid inlet 12 through the liquid inlet pipe 11, so that the lubricating oil can flow into the guide rail 6 through the first liquid inlet 12, so as to achieve the lubrication of the guide rail 6, and make the slide plate 7 move more smoothly in the guide rail 6. Since the second liquid inlet 13 is connected to the first liquid inlet 12, some lubricating oil will flow into the connecting rail 8 through the second liquid inlet 13, so as to achieve the lubrication of the connecting rail 8, and make the guide block 9 move more smoothly in the connecting rail 8.
