Description

Technical Field

[0001] The invention belongs to the technical field of engineering elevators, and in particular relates to a safe lifting elevator for construction engineering. Background Art

[0002] In the construction field, operations often have to be performed at high altitudes, so an aerial work platform is needed. Various hoists and lifting devices are widely used in construction equipment today. When working at high altitudes, various tools need to be carried. Due to the numerous and complicated tasks, people may forget to close the door, and there is a risk of tools falling. Some existing construction engineering elevators do not deal with this hidden danger, and thus cannot ensure the safety of personnel. Therefore, a safe lifting elevator for construction engineering is proposed to solve the above problem. Summary of the invention

[0003] The purpose of the present invention is to provide a safe lifting elevator for construction projects, so as to solve the problem that some existing construction engineering elevators need to carry various tools when working at high altitudes. Due to the numerous and complicated tasks, people may forget to close the door, and there is a risk of tools falling, thus failing to ensure the safety of personnel.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The present invention is a safety lifting elevator for construction projects, comprising a fixed bottom plate, an elevator box, a second extrusion spring and a connecting column, a surface of the fixed bottom plate is provided with a slot, a front surface of the elevator box is slidably connected with a protective door, an inner slide groove is provided in the elevator box, an extrusion rod is slidably connected in the inner slide groove, a hollow column is fixedly installed at the bottom of the elevator box, a locking block is slidably connected to the front surface of the hollow column, a first fixed rod and a second fixed rod are fixedly installed in the hollow column, and a first side slide plate and a second side slide plate are respectively fixedly installed at both ends of the locking block.

[0006] The extrusion rod is fixedly installed through a connecting column and a first side slide plate, the extrusion rod is against the inner surface of the protective door, and the outer end of the extrusion rod is preferably a chamfered surface.

[0007] The first fixing rod and the second fixing rod are both sleeved with a first extrusion spring on their circumferential sides, the second extrusion spring is located in the inner slide groove and abuts against the inner end of the extrusion rod, the slot opening and the locking block are adapted to each other in size, the slot opening and the locking block are engaged with each other, and by setting the slot opening and the locking block, when the locking block is locked in the slot opening, the elevator box and the fixed base plate are fixed.

[0008] The locking block is slidably connected to the first fixing rod through the second side slide plate at one end, and is slidably connected to the second fixing rod through the first side slide plate at the other end.

[0009] The two first extrusion springs are respectively located on the peripheral sides of the first fixing rod and the second fixing rod, and the two first extrusion springs are respectively against the first side slide plate and the second side slide plate.

[0010] The present invention has the following beneficial effects:

[0011] The present invention fixes the elevator box on the fixed bottom plate through the card slot and the locking card block, so that the elevator box is fixed on the fixed bottom plate and cannot rise. When the protective door slides to the closed state, the inner wall of the protective door and the extrusion rod are squeezed together, so that the extrusion rod is squeezed into the inner slide groove, and the inner end of the extrusion rod drives the locking card block to move inwardly through the connecting column. At this time, the locking card block is disengaged from the card slot, and the elevator box can start to rise. The protective door of the present invention will be fixed when it is not closed, thereby avoiding the risk of tools falling when forgetting to close the protective door, thereby failing to ensure the safety of personnel.

[0012] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0025] See also Figure 1-Figure 6 As shown, the present invention is a safety lifting elevator for construction engineering, comprising a fixed bottom plate 1, an elevator box 2, a second extrusion spring 8 and a connecting column 10, a surface of the fixed bottom plate 1 is provided with a card slot 4, a front surface of the elevator box 2 is slidably connected with a protective door 3, an inner slide groove 7 is provided in the elevator box 2, an extrusion rod 5 is slidably connected in the inner slide groove 7, a hollow column 9 is fixedly installed at the bottom of the elevator box 2, a locking block 13 is slidably connected to the front surface of the hollow column 9, a first fixed rod 14 and a second fixed rod 15 are fixedly installed in the hollow column 9, and a first side slide plate 11 and a second side slide plate 12 are fixedly installed at both ends of the locking block 13.

[0026] Among them, the first fixed rod 14 and the second fixed rod 15 are both sleeved with the first extrusion spring 6 on the surrounding side surfaces, the second extrusion spring 8 is located in the inner slide groove 7 and abuts against the inner end of the extrusion rod 5, the extrusion rod 5 abuts against the inner surface of the protective door 3, and the extrusion rod 5 is fixedly installed by the connecting column 10 and the first side slide plate 11.

[0027] Moreover, the locking block 13 is slidably connected to the first fixed rod 14 through the second side slide 12 at one end, and the other end of the locking block 13 is slidably connected to the first side slide 11 and the second fixed rod 15.

[0028] Moreover, the sizes of the slot 4 and the locking block 13 are adapted to each other, and the slot 4 and the locking block 13 are engaged with each other.

[0029] like Figure 1-Figure 6 As shown, this embodiment is a method for using a safety elevator for construction engineering: the outer end of the extrusion rod 5 is preferably a chamfered surface, so that the protective door 3 and the extrusion rod 5 can abut against each other. When the elevator box 2 descends, the locking block 13 is squeezed and stuck in the card slot 4. At this time, the elevator box 2 is fixed on the fixed bottom plate 1 and cannot rise;

[0030] When the protective door 3 slides to the closed state, the inner wall of the protective door 3 and the squeezing rod 5 are squeezed together, so that the squeezing rod 5 is squeezed into the inner slide groove 7, and the inner end of the squeezing rod 5 drives the locking block 13 to move inward through the connecting column 10. At this time, the locking block 13 is disengaged from the slot 4, and the elevator car 2 can be raised.

[0031] The present invention fixes the elevator box 2 on the fixed bottom plate 1 and cannot rise by fixing the slot 4 and the locking block 13. When the protective door 3 slides to the closed state, the inner wall of the protective door 3 and the extrusion rod are squeezed together, so that the extrusion rod 5 is squeezed into the inner slide groove, and the inner end of the extrusion rod 5 drives the locking block 13 to move inward through the connecting column 10. At this time, the locking block 13 is disengaged from the slot 4, and the elevator box 2 can start to rise. The protective door 3 of the present invention will be fixed when it is not closed, thereby avoiding the risk of tools falling when forgetting to close the protective door 3, thereby failing to ensure the safety of personnel.
