Description
Technical Field
The invention relates to the technical field of elevator measuring equipment, in particular to an elevator landing door sliding block meshing depth measuring ruler.
Background
The elevator landing door is a device which is firstly contacted by passengers when the elevator is used, and is an important part for ensuring the safety of the elevator and the passengers, so that the transition and the isolation of the elevator and a building are realized, a relatively closed isolation protection is formed between an elevator shaft and a building channel, and the accidents caused by the falling of the personnel from the shaft are prevented. In recent years, accidents caused by the fact that personnel outside the landing door accidentally fall into an elevator shaft have occurred many times at home and abroad, and most of the accidents are caused by the fact that the landing door leaves deform or a sliding block is separated from a sliding groove due to the fact that the landing door is impacted by outside horizontal acting force, so that the landing door leaves are displaced and form a gap with a building. According to the structural analysis of the elevator landing door, when the elevator landing door is impacted by a horizontal or approximately horizontal external force, the door leaf generates a reaction force through the mechanical strength of the door leaf, an upper guide device and a lower sliding block of the door leaf so as to keep the landing door stable at a working position, and most of the external force acts on the lower part of the door leaf; the mechanical strength of the landing door leaf and the depth of engagement of the lower sliding block with its sliding groove are therefore of great importance. Therefore, when the elevator is subjected to daily maintenance, self-inspection, supervision and inspection and periodic inspection, the engagement depth of the landing door guide shoes is required to be measured, but because the elevator landing door sliding block is engaged with the sliding groove of the elevator landing door sliding block at a hidden position, even if the elevator car is operated in an inspection state and stands on a car top inspection platform for measurement, direct measurement cannot be conveniently and quickly carried out due to narrow space. In the prior art, the engagement depth of the sliding block and the sliding groove is measured, the groove depth is measured, the gap between the bottom of the sliding block and the bottom of the sliding groove is measured, and then the gap between the bottom of the sliding block and the bottom of the sliding groove is subtracted by the depth of the sliding groove, so that the operation is inconvenient. In summary, a direct, convenient and accurate measuring ruler needs to be designed.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: because the elevator landing door sliding block is meshed with the sliding groove of the elevator landing door sliding block at a hidden position, even if the elevator car is operated in an overhaul state and stands on a car top overhaul platform for measurement, the elevator landing door sliding block cannot be conveniently and quickly directly measured due to narrow space.
In order to solve the problems, the technical scheme adopted by the invention is as follows: a sliding block meshing depth measuring scale for an elevator landing door comprises a main body transversely arranged in a sliding groove of a landing door sill, wherein a wedge-shaped measuring sliding block and a wedge-shaped measuring sliding block are arranged in the main body in parallel from front to back, and the wedge-shaped measuring sliding block are fixedly connected through a connecting piece; a ruler frame is vertically arranged above the wedge-shaped measuring slide block of the main body, and a vernier scale which can be lifted and is provided with scales is sleeved in the ruler frame; one end of the vernier penetrates through the main body to be in contact with the upper surface of the wedge-shaped measuring slide block, and profile figures formed on the longitudinal section of the wedge-shaped measuring slide block and the wedge-shaped measuring slide block are identical.
The beneficial effects of the invention are as follows: the principle of equivalent transfer of parallel arrangement of congruent triangles is utilized, the gaps of the limited positions are extended in equivalent, the favorable condition of direct measurement is formed, and the requirements of convenience, rapidness, direct measurement and accuracy are met by matching a special measuring scale.
As a further improvement of the invention, the technical problems to be solved are as follows: how to further use the vernier for the calibration measurement of the depth value.
In order to solve the technical problems, the invention further adopts the following improved technical scheme: the outside of the ruler frame is sleeved with a zero calibration device which can be lifted and adjusted, and one side of the ruler frame of the zero calibration device is provided with a vernier locknut.
The beneficial effect of the improvement is as follows: zero calibration and locking of multiple measurement of the vernier are realized; further obtain more accurate measuring result, promote the convenience of operation simultaneously.
As a further improvement of the invention, the technical problems to be solved are as follows: how to more conveniently operate the wedge-shaped quantity sliding block to accurately and stably move.
In order to solve the technical problems, the invention further adopts the following improved technical scheme: the main body is provided with a limiting sliding groove above the connecting piece, and a push rod capable of sliding back and forth is arranged in the limiting sliding groove; the bottom of the push rod is fixedly connected with the connecting piece.
The beneficial effect of the improvement is as follows: the push rod arranged above the main body can help a measurer to push the wedge-shaped measuring slide block more conveniently, so that the wedge-shaped measuring slide block is driven by the connecting piece to penetrate into the lower part of the sliding block of the landing door rapidly.
As a further improvement of the invention, the technical problems to be solved are as follows: if the sliding block of the landing door is too high, the measuring depth is too large; the bottom end of the sliding block of the landing door passes over the wedge-shaped measuring sliding block, and the rear ruler frame and the zero calibration device can be damaged.
In order to solve the technical problems, the invention further adopts the following improved technical scheme: the main body is provided with a limiting block used for limiting the sliding block of the layer door at the rear end of the wedge-shaped measuring sliding block.
The beneficial effect of the improvement is as follows: the setting of the limiting block reminds a measurement worker; and meanwhile, the structure behind the automobile bumper is effectively protected from collision damage.
