Technical Field

[0001] The utility model relates to the technical field of freight elevators, in particular to a freight elevator which is convenient for going up and down. Background Art

[0002] With the development and iteration of elevators, elevators are divided into passenger elevators and freight elevators according to their design and use. Most elevators are inseparable from the important component of the car. The car is a rectangular box with a door on one side. The door is opened when loading is required, and then the goods to be transported are pushed into the box. However, most freight elevators have a small internal space, which causes the porters to be hindered when transporting the goods due to the limited space in the elevator. Especially when transporting large goods, the limited space in the car greatly restrains the porters' bodies, making it difficult for the goods to enter the car, causing the elevator to be occupied for a long time and affecting the efficiency of transporting goods.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the freight elevator which is convenient for going up and down:

[0018] 1. When transporting goods, the goods can be neatly stacked on the push truck first, and then the push truck can be moved from the warehouse to the freight elevator, and pushed into the interior of the elevator car. During the pushing process, the solid wheels will contact the guide rails, so that the solid wheels will automatically align along the inclined surface of the guide rails, so that the push truck will not collide with the elevator car, increasing the operating space during transportation and facilitating the transportation of goods, while improving the efficiency of the freight elevator;

At the same time, after reaching the floor for unloading goods, the drive motor rotates in the opposite direction to drive the buckle rod to push the push cart out, making it easier for the porter to push the push cart in and out of the car. At the same time, when the fixed slider engages with the buckle rod, there is no need to operate manually, which saves the physical strength consumed by the porter when transporting goods and reduces the number of operation steps;

[0020] 3. When the steel cable slips during operation, the inspection stand can be removed from the car, and the first fixed pulley, the second fixed pulley and the steel cable can be inspected and adjusted. When the steel cable cannot be used and replaced with a new one, the steel cable can be passed through the first fixed pulley and the second fixed pulley, and the clamping wedges at both ends of the steel cable can be placed on one end of the buckle rod. Then the fixed block is connected to the buckle rod, so that the fixed block squeezes the clamping wedge through the inclined surface, so that the steel cable is gradually tightened, and the two ends of the steel cable are fixed by pressing the fixed block and the buckle rod, so that the steel cable is fixed more firmly and automatically shortened and tightened, thereby extending the service life of the steel cable and reducing the chance of slipping.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6 The utility model provides a technical solution: a freight elevator which is convenient for going up and down, comprising a frame 1, a hydraulic cylinder 2 is fixedly installed on the outer surface of the frame 1, and the output end of the hydraulic cylinder 2 passes through the outer surface of the frame 1, one end of the frame 1 close to the hydraulic cylinder 2 is buried underground, and a car 3 is fixedly installed on the output end of the hydraulic cylinder 2, the car 3 is located inside the frame 1, and the frame 1 and the car 3 are slidably connected, a door is provided on the outer surface of one end of the car 3, and a push truck 5 is provided inside the car 3, and a limited guide mechanism is provided between the interior of the car 3 and the push truck 5, through which the push truck 5 with neatly stacked goods can quickly and without collision enter the interior of the car 3.

[0030] When the goods need to be transported, the push truck 5 can be pushed to the warehouse and the goods can be neatly stacked on the push truck 5. Then, the push truck 5 can be moved at will through the solid wheels 6 and transported to the entrance and exit of the freight elevator, so that workers do not need to enter the car 3 when transporting the goods, which expands the operating space during transportation and reduces the occupancy time of the freight elevator.

[0031] The guide mechanism comprises a guide track 4 , one end of which is inclined, and solid wheels 6 are rotatably mounted on the outer surfaces of both sides of the push truck 5 , and the side surfaces of the solid wheels 6 are in contact with the outer surface of the guide track 4 .

[0032] When the push truck 5 is pushed into the car 3, the guide rail 4 will contact the solid wheel 6, so that the solid wheel 6 will move along the inclined surface of the guide rail 4 to automatically align, thereby reducing the collision between the push truck 5 and the car 3, and reducing the possibility of goods falling from the push truck 5 due to collision, so that the push truck 5 can be smoothly and directly pushed into the car 3 without adjustment.

[0033] A rotating mechanism is provided inside the car 3, through which the push truck 5 can be assisted to be pushed into the interior of the car 3, saving the effort of the porters. The rotating mechanism includes: a drive motor 10, which is fixedly mounted on the outer surfaces of both sides of the car 3, and a second fixed pulley 12 is rotatably installed inside the car 3, a first fixed pulley 11 is fixedly mounted on the output end of the drive motor 10, and the first fixed pulley 11 is rotatably connected to the car 3, a steel cable 13 is provided between the first fixed pulley 11 and the second fixed pulley 12, and the steel cable 13 is engaged with the first fixed pulley 11 and the second fixed pulley 12, a buckle rod 9 is slidably installed inside the car 3, and the buckle rod 9 is connected to the steel cable 13, the buckle rod 9 is V-shaped, and the buckle rod 9 is connected to the push truck 5.

[0034] The push truck 5 is pushed toward the locking rod 9 so that the inclined surface of the fixed slider 7 contacts the locking rod 9. As the push truck 5 is pushed forward, the fixed slider 7 moves on the outer surface of the push truck 5 and engages with the locking rod 9. Then, the driving motor 10 can be started to drive the first fixed pulley 11 to rotate, so that the first fixed pulley 11 drives the second fixed pulley 12 to rotate through the steel cable 13, so that the locking rod 9 slides inside the car 3, and the locking rod 9 is pulled into the car 3 by the movement of the locking rod 9, and then the door outside the car 3 is closed, and then the hydraulic cylinder 2 is started to drive the car 3 to move, so that the car 3 moves along the direction of the frame 1. When the car 3 reaches the unloading floor, the first fixed pulley 11 is driven to reverse by starting the driving motor 10, so that the locking rod 9 is reversed together to push the push truck 5 out of the car 3, and the push and pull back of the porter assists the push truck 5 to enter and push out of the car 3, saving the porter's physical strength when transporting goods.

[0035] A sliding mechanism is provided between the locking rod 9 and the pushing truck 5, through which the pushing truck 5 can be automatically connected to the locking rod 9 when it is pushed into the car 3.

[0036] When the car 3 is opened, due to the V-shaped design of the buckling rod 9, a part of the buckling rod 9 is located outside the car 3. At this time, the push truck 5 is pushed toward the buckling rod 9, so that the fixed slider 7 contacts the buckling rod 9, and the fixed slider 7 moves and engages with the buckling rod 9 through the inclined surface of the fixed slider 7, so that the push truck 5 does not need to be aligned when entering the interior of the car 3. As the buckling rod 9 moves into the car 3, the contact between the solid wheel 6 and the guide rail 4 allows the push truck 5 to automatically align, so that the fixed slider 7 slides on the outer surface of the buckling rod 9, so that the push truck 5 is automatically corrected and squeezed into the car 3. After the goods are transported to the designated floor, the buckling rod 9 moves to push the push truck 5 out of the car 3. At this time, when the push truck 5 needs to be taken out, it only needs to push the pull rod 8, so that the fixed slider 7 can slide inside the push truck 5 and disengage from the buckling rod 9, so that the push truck 5 can be automatically locked after being pushed toward the buckling rod 9, and the time for the porter to find the door of the car 3 is saved, thereby improving the use efficiency of the freight elevator.

[0037] Fixed blocks 15 are fixedly installed at both ends of the buckling rod 9, and the outer surface of the fixed block 15 is in contact with the outer surface of the steel cable 13.

When the steel cable 13 cannot be used, a new steel cable 13 can be replaced, the steel cable 13 is passed through the first fixed pulley 11 and the second fixed pulley 12, and the clamping wedges 14 at both ends of the steel cable 13 are placed on one end of the buckling rod 9, and then the fixing block 15 and the buckling rod 9 are connected and fixed to each other. The steel cable 13 is automatically shortened and tightened by the squeezing of the clamping wedge 14 by the fixing block 15, and the clamping of the steel cable 13 by the fixing block 15 and the buckling rod 9 and the fitting of the clamping wedge 14, so that the connection between the two ends of the steel cable 13 and the buckling rod 9 can be more stable, thereby improving the fixing stability and service life of the steel cable 13.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
