Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0023] according to Figure 1-6 As shown, a hydraulic guide rail type lifting freight elevator includes a foundation 1, an installation groove 2 is formed on the top surface of the foundation 1, a support base 3 is fixedly installed in the installation groove 2, a freight elevator frame 4 is fixedly installed on the support base 3, a hydraulic drive mechanism and a chain lifting assembly are installed on the freight elevator frame 4, a car 5 is installed on the chain lifting assembly, a balance lifting assembly is provided at the bottom of the car 5, a base plate 6 is provided below the car 5, a pressure sensor 7 is installed at the bottom of the base plate 6, and the pressure sensor 7 is fixedly installed on the support base 3.

[0024] In this embodiment, the freight elevator frame 4 includes a top frame 8. Support columns 9 are vertically installed at the bottom of the top frame 8 near its four endpoints. The support columns 9 are fixedly installed on the support base 3. A hydraulic drive mechanism is installed on the left and right sides of the freight elevator frame 4. The hydraulic drive mechanism includes multiple sets of lifting hydraulic cylinders 10. A fixing frame 11 is fixedly installed at the bottom end of the support columns 9 on the same side. Multiple sets of lifting hydraulic cylinders 10 are fixedly installed on the fixing frame 11. Preferably, there are two sets of lifting hydraulic cylinders 10. The lifting hydraulic cylinders 10 are vertically installed on the fixing frame 11. A lifting plate 12 is fixedly installed at the power output end of the lifting hydraulic cylinder 10. Guide rails 13 are fixedly installed on the support columns 9 on the front and rear sides of the lifting plate 12. The lifting plate 12 is slidably connected to the guide rails 13. A chain lifting assembly is installed on the top of the lifting plate 12. The lifting assembly includes multiple sets of first sprocket seats 14, preferably two sets. The first sprocket seats 14 are fixedly installed on the top of the lifting plate 12. A connecting rod 15 is fixedly installed between the rotating shafts of each set of first sprocket seats 14. A lifting chain 16 is installed on each set of first sprocket seats 14. The car 5 is fixedly connected to one end of the lifting chain 16. A fixing plate 17 is fixedly installed on the other end of the lifting chain 16. The fixing plate 17 is fixedly installed on the support column 9. When the car 9 is raised or lowered, the lifting plate 12 is raised or lowered by the lifting hydraulic cylinder 10. The two ends of the lifting plate 12 slide smoothly in the guide rails 13 of the two support columns 9. The connecting rod 15 makes the two sets of first sprocket seats 14 rotate synchronously, so that the lifting chains 16 on both sides of the car 9 lift the car 9 synchronously, enhancing the stability of the lifting.

[0025] In this embodiment, the balancing lifting assembly includes multiple sets of second sprocket seats 18. The second sprocket seats 18 are installed at the bottom left and right ends of the car 5. A balancing chain 19 is installed on the second sprocket seats 18. One end of the balancing chain 19 is fixedly connected to the bottom of the support column 9 on one side of the car 5. After meshing with the top of the second sprocket seat 18 on one side of the car 5 and the bottom of the second sprocket seat 18 on the other side, the other end is fixedly connected to the top of the support seat 22 on the other side of the car 5. The balancing lifting assemblies are arranged in pairs at the bottom of the car 5. Each set of balancing lifting assemblies has two sets of balancing chains 19. The two sets of balancing chains 19 are arranged in opposite directions at the bottom of the car 5. The multiple sets of second sprocket seats 18 and the alternately arranged balancing chains 19 provide bottom support for the lifting of the car 5 and reduce the shaking of the car 5 during operation.

[0026] In this embodiment, a brake groove 20 is fixedly installed on the side of each support column 9 near the car 5. A brake block 21 matching the brake groove 20 is provided at the bottom of the car 5. The brake block 21 is slidably installed on the support seat 22. The support seat 22 is fixedly installed at the bottom of the car 5. An anti-fall hydraulic cylinder 23 is provided on the side of the support seat 22 away from the support column 9. The power output end of the anti-fall hydraulic cylinder 23 is fixedly connected to the brake block 21. When the car 5 falls unexpectedly, the anti-fall hydraulic cylinder 23 drives the brake block 21 to move closer to the brake groove 20, providing safety protection for the car 5 and preventing it from falling.

[0027] In this embodiment, an infrared sensor 24 is fixedly installed at the end of the car 5. The infrared sensor 24 extends to both sides along the side of the car 5 and is located at the entrance of the freight elevator. When the car 5 descends, the infrared sensor 24 detects whether a person or object has entered the freight elevator.

[0028] In use, this utility model uses a lifting hydraulic cylinder 10 to lift the lifting plate 12, which in turn causes the first sprocket seat 14 to move the lifting chain 16. This allows the lifting chains 16 on both sides of the car 9 to lift the car 9 synchronously. The anti-fall hydraulic cylinder 23 provides safety protection for the car 5. When the car 5 is raised and a person or object enters the freight elevator shaft, it will press down on the bottom plate 6 and trigger the pressure sensor 7. At this time, the lifting hydraulic cylinder 10 stops working, stopping the car 5 from moving to prevent safety accidents. The pressure sensor can also be connected to a speaker to remind staff to leave the freight elevator shaft. In addition, when the car 5 is descending, the infrared sensor 24 detects whether a person or object has entered the freight elevator shaft, further ensuring the safety of the freight elevator during operation.

[0029] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. The scope of protection of this utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this utility model.
