Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a safety transportation limiting device for a standardized construction elevator. Background Art

[0002] At construction sites, elevators are usually needed to carry people or goods to facilitate the transportation of workers between different floors. The anti-collision devices used in elevator cars at domestic construction sites are mostly fixed on one side, and the cross bar used for anti-collision cannot be fixed after it is opened. An operator is required to open the cross bar and keep it in an open state, which makes the operation of material transporters too cumbersome.

[0003] However, the problem that the existing elevators are difficult to limit during use has not been solved, so that the impact energy of the single-sided fixation cannot be fully transmitted to both sides of the car, and the pressure direction of the cross bar impact is obliquely downward. If there is no reliable reaction force at the bottom, the cross bar is very easy to fall off, affecting the safety of the operator in the car. For this reason, we propose a standardized construction elevator safety transportation limit device. Utility Model Content

[0004] In view of the above problems, the utility model provides a safe transportation limit device for a standardized construction elevator, which provides greater safety for construction personnel, facilitates entry and exit of workers when transporting materials, effectively limits the position, and enters the car by simply opening the elevator door, which is easy to operate.

[0005] The technical solution of the utility model is: a standardized construction elevator safety transportation limit device, including columns, limit railings and an elevator car, the columns are fixed in pairs on both sides of the inner wall of the elevator car by angle steels, and the side of the column away from the elevator car is welded and connected with two symmetrically arranged galvanized steel bearing plates, the galvanized steel bearing plates are welded and connected with obliquely cut fixed round steel pipes, a pin is inserted in the upper group of galvanized steel bearing plates, a second spring is inserted in the lower group of galvanized steel bearing plates, and a pin is inserted on the surface of the upper galvanized steel bearing plate.

[0006] In a further technical solution, the limiting railing includes a horizontal bar and a vertical bar. The horizontal bar is respectively fitted with the galvanized steel bearing plates at the upper and lower ends. Four symmetrically arranged vertical bars are welded to the inner wall of the horizontal bar. The upper end of the horizontal bar is welded to an obliquely cut rotating round steel pipe, and the lower end of the horizontal bar is welded to a flat-cut round steel pipe.

[0007] In a further technical solution, the number of the galvanized steel bearing plates is four, and the galvanized steel bearing plates are distributed in groups of two.

[0008] In a further technical solution, the pin shaft and the second spring respectively penetrate the surface of the galvanized steel bearing plate.

[0009] In a further technical solution, a first spring is fixedly connected inside the flat-cut circular steel pipe, and the first spring is used to improve the resetting effect of the limit railing.

[0010] The beneficial effects of the utility model are:

[0011] 1. The limit railings, elevator car, pin shafts and pins cooperate with each other, so that the elevator car can be convenient for workers to carry materials when in use. The limit railings are set to improve the protection effect in the elevator car. At this time, the pin shaft can cooperate with the pin to position the limit railing, thereby achieving the effect of facilitating the improvement of protection and preventing inconvenience in manual operation and poor protection effect.

[0018] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0019] Example:

[0020] like Figure 1-Figure 4As shown, a standardized construction elevator safety transportation limit device includes a column 1, a limit railing 2 and an elevator car 3. The columns 1 are fixed in pairs on both sides of the inner wall of the elevator car 3 by angle steels. The side of the column 1 away from the elevator car 3 is welded with two symmetrically arranged galvanized steel bearing plates 1-1, and the galvanized steel bearing plates 1-1 are welded with an obliquely cut fixed round steel pipe 1-2. The number of galvanized steel bearing plates 1-1 is four, and the galvanized steel bearing plates 1-1 are distributed in groups of two. A pin shaft 4 is inserted in the upper group of galvanized steel bearing plates 1-1, and a second spring 6 is inserted in the lower group of galvanized steel bearing plates 1-1. The pin shaft 4 and the second spring 6 respectively penetrate the surface of the galvanized steel bearing plate 1-1, and a pin 5 is inserted in the surface of the upper galvanized steel bearing plate 1-1.

[0021] The working principle of the above technical solution is as follows:

[0022] When it is necessary to protect the elevator car 3 during operation, the unfolded limit railing 2 can be held by hand and flipped to the closed state. After the limit railing 2 is flipped, the pin shaft 4 and the second spring 6 set at this time can cooperate with the limit railing 2 to rotate with the galvanized steel bearing plate 1-1, so as to limit the limit railing 2 and make it flippable. At this time, the limit railing 2 can be conveniently entered into building materials and manual entry after being unfolded. After entry is completed, the limit railing 2 can be held by hand and flipped to the closed state, and then the pin 5 can be held by hand and inserted into the upper end pin shaft 4 to position and limit the cross bar 2-1, so as to locate the position of the limit railing 2 to prevent the limit railing 2 from flipping over and the protection effect is poor, thereby providing construction personnel with more safety protection, and workers can enter and exit conveniently and effectively limit when carrying materials.

[0023] In another embodiment, if Figure 2 and Figure 3 as well as Figure 4 As shown, the limit railing 2 includes a cross bar 2-1 and a vertical bar 2-2. The cross bar 2-1 is respectively fitted with the galvanized steel bearing plates 1-1 at the upper and lower ends. The inner wall of the cross bar 2-1 is welded with four symmetrically arranged vertical bars 2-2. The upper cross bar 2-1 is welded with an obliquely cut rotating round steel pipe 2-3, and the lower cross bar 2-1 is welded with a flat-cut round steel pipe 2-4. The inside of the flat-cut round steel pipe 2-4 is fixedly connected with a first spring 2-4-1. The first spring 2-4-1 is used to improve the resetting effect of the limit railing 2.

[0024] The limit railing 2 is arranged to cooperate with the horizontal bar 2-1 and the vertical bar 2-2 to block users and building materials. The flat-cut circular steel pipe 2-4 can conveniently drive the limit railing 2 to return to the ready working state through the first spring 2-4-1, so that the limit railing 2 can be easily reset. The vertical bar 2-2 can improve the overall stability of the limit railing 2. Since the horizontal bar 2-1 and the vertical bar 2-2 are both made of galvanized steel plates, the overall protection effect is improved, the protection and convenience of use are achieved, and the safety effect of the staff is improved.

[0025] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
