Background

The lintel arranged in the elevator car is mainly used to provide accommodation space for the door machine of the elevator. The fixed position of the door lintel can be influenced by inconsistent elevator width and elevator door opening eccentric angle under each elevator or different installation scenes, so that the structure of the elevator door lintel needs to be designed according to the actual size of the elevator. If the universal door lintel can be provided and is suitable for the installation of elevators with various structures, the production cost of elevator manufacturers can be reduced.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the integrated door lintel is universal and can be adapted to installation of elevators with various specifications.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows:

the integrated elevator door lintel comprises a door lintel plate and two supports, wherein the door lintel plate is formed by integrally bending metal plates and comprises a vertical flat plate, an upper baffle and a lower baffle, the upper baffle is vertically connected to the top of the flat plate, and the lower baffle is vertically connected to the bottom of the flat plate; the brackets are arranged at the top of the lower baffle, and a group of strip-shaped through holes which are arranged along the length of the door lintel plate in a square manner are arranged on the lower baffle corresponding to each bracket; the support is L type, is provided with the installation regulation hole one of bar on its bottom plate, is provided with the installation regulation hole two of bar on its riser to a bolt passes installation regulation hole one and through-hole will the support is fixed in down on the baffle.

In order to solve the technical problem, the invention adopts another technical scheme as follows:

a door lintel fixing structure is characterized by comprising two supporting feet and the integrated elevator door lintel; a side plate of the supporting leg is attached to a vertical plate of the support, a U-shaped jack is arranged in the side plate, and the supporting leg is fixedly connected with the support by a bolt penetrating through the U-shaped jack and a mounting adjusting hole II; the supporting legs further comprise connecting plates parallel to the door lintel plate, strip-shaped through holes II are formed in the connecting plates, and a bolt penetrates through the through holes II to be locked into the door machine body.

Compared with the prior art, the invention has the beneficial effects that:

1. the position of the bracket of the integrated door lintel can be adjusted according to the hole position of the mounting hole of the gantry crane, and the addition of the bracket ensures that the door lintel can be matched with various gantry cranes to be mounted on the premise of not changing the original structure;

2. the position of the supporting leg is combined with the position of the support to be adjusted, so that the mounting hole position of the door machine body can be matched more accurately, the mounting interference is reduced, and the stability of the elevator during operation is improved.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

Examples

The elevator door lintel shown in fig. 1 comprises a lintel plate, the inner side of which is provided with vertical stiffening plates 20, and two supports 10. The door lintel plate 30 is formed by integrally bending a sheet metal and comprises a vertical flat plate 31, an upper baffle 32 and a lower baffle 33, wherein the upper baffle is vertically connected to the top of the flat plate, the lower baffle is vertically connected to the bottom of the flat plate, and a backup plate 34 parallel to the door lintel plate is preferably formed by bending the side surface of the lower baffle. The support mounting is in the top of baffle down, corresponds each support on the baffle down and all is provided with a set of bar through-hole 35 along lintel board length square arrangement. Referring to fig. 2, the support is L-shaped, a strip-shaped mounting adjusting hole I12 is formed in a bottom plate 11 of the support, the support is placed on the lower baffle, the mounting adjusting hole I and the through hole are overlapped to form a screw through hole, and a bolt penetrates through the mounting screw through hole to fix the support on the lower baffle. The support position of integral type lintel can be adjusted according to the hole site of door machine mounting hole, and the increase of support makes the lintel can match multiple door machine installation under the prerequisite that does not change original structure.

The vertical plate 13 of the bracket is provided with a strip-shaped mounting adjusting hole II 14.

Referring to fig. 3, the side plate 41 of the support foot 40 is provided with a U-shaped insertion hole 42 therein, and a connecting plate 43 of the support foot is parallel to the lintel plate, and is preferably of an integral structure. The connecting plate is provided with a second strip-shaped through hole 44. Referring to fig. 4 and 5, the side plates of the supporting plate are attached to the vertical plates of the bracket, the supporting legs are fixedly connected to the bracket by a bolt penetrating through the U-shaped insertion hole and the mounting adjusting hole II, and the supporting legs are locked into the door machine body 50 by a bolt penetrating through the through hole II. The position of the supporting leg is combined with the position of the support to be adjusted, so that the mounting hole position of the door machine body can be matched more accurately, the mounting interference is reduced, and the stability of the elevator during operation is improved.
