Abstract

The invention relates to a buried elevator's safely lifting platform that relates to the lifting platform surrounded with several stuck out protective plate, whose hinging part with the lifting platform rotating above the lifting platform, the said safety lifting platform set at the end of the protective rotary axial end with protective device. It can effectively solve the issue of being unable to rotate of the adjacent protective plate along the rotary axial line sticking out the lifting platform to protect man, and property.

Description

The safety lifting platform of latent elevator

Technical field

The present invention relates to a kind of safety method field of elevator; Especially the safety lifting platform that relates to a kind of latent elevator.

Background technology

At present, submerged lifting table commonly used has hydraulic up-down platform or electrodynamic type lifting table, all is that the work by jacking system realizes that the lifting of lifting table is to realize the work of elevator.In this equipment work, its lifting table usually is falling into below the mounting plane gradually, from people's the visual field, disappear, be difficult for attracting much attention, people enter the working space of lifting table easily, cause crowded wound easily, have safety hazard, the safety of threat to life and property pin or other people body region.Have in the existing latent elevator on the lifting table of elevator, to cut with scissors to tie to be provided with mobile protective panel,, realize protection people or property by controlling lifting table with the master cock of guar plate interlock.But; if guar plate adjacent in these elevators is movable together with in the safety of protecting people or property; the part of stretching out lifting table along its rotation axis in these two adjacent guar plates just might not can rotate; people or property generation are pushed and damage, thereby out of reach is to the purpose of people or property protection.

Summary of the invention

The technical problem to be solved in the present invention has provided a kind of safety lifting platform of latent elevator; but its actv. solves in the elevator in two adjacent on the lifting table guar plates along its rotation axis and stretches out the problem that the part of lifting table can not rotate, and reaches the purpose to people or property protection.

For solving the problems of the technologies described above, technical scheme of the present invention is: the safety lifting platform of latent elevator, the lifting table that relates to elevator, lifting table peripheral hinged is provided with the guar plate that multi-disc is stretched out lifting table, guar plate is that axial line rotates above lifting table with the hinge knot place with lifting table, and the place, end that described safety lifting platform is positioned at the guar plate rotation axis also is provided with protective device.As a kind of improvement, described lifting table is square, and described guar plate is located on each limit of lifting table, and the shaft center line of guar plate is parallel to each limit of lifting table.

As further improvement, described protective device comprises and is arranged in that the hinge knot is provided with rebound on adjacent two guar plates, one guar plate on each angle of lifting table.

As further improvement, described protective device is for being the diagonal formula cooperation between adjacent two guar plates on each angle of lifting table.

As further improvement, described protective device is included in to cut with scissors to tie between adjacent two backplates of locating at each angle of lifting table and is provided with the transition guar plate, and the transition guar plate intersects respectively around the shaft center line of hinge knot place's rotation and shaft center line and adjacent two guar plates.

As further improvement, the shaft center line of described transition guar plate equates with the angle of the shaft center line of adjacent two guar plates.

As further improvement, also be provided with master cock on the described lifting table with the guar plate interlock.

Adopt the safety lifting platform of the latent elevator of said structure, stretch out the flat-bed guar plate by on lifting table, being hinged with, guar plate can prevent that the workman from advancing the working space of people's lifting table, the master cock of guar plate interlock is controlled the work of jacking system by the control power control, and also is provided with protective device at the place, end that safety lifting platform is positioned at the guar plate rotation axis.Such structure; the part of having avoided stretching out lifting table along the guar plate rotation axis may not can rotate, and people or property are produced the problem of pushing and damaging, thereby reaches the purpose to people or property protection; avoid people or article are caused damage, and simple in structure, cost is low.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described:

Fig. 1 is the structural representation of the safety lifting platform of latent elevator of the present invention;

Fig. 2 is the scheme drawing of safety lifting platform one embodiment of latent elevator of the present invention;

Fig. 3 is the scheme drawing of another embodiment of safety lifting platform of latent elevator of the present invention;

Fig. 4 is the scheme drawing of another embodiment of safety lifting platform of latent elevator of the present invention.

The specific embodiment

With reference to Fig. 1, the safety lifting platform of a kind of latent elevator of the present invention is: the lifting table 1 that relates to elevator, this safety lifting platform is provided with the jacking system 4 that promotes lifting table 1, the power control of may command jacking system 4 work, periphery hinge knot at lifting table 1 is provided with the guar plate 2 that multi-disc is stretched out lifting table 1, guar plate 2 is that axial line rotates above lifting table 1 with the hinge knot place with lifting table 1, and the place, end that safety lifting platform is positioned at guar plate 2 rotation axiss also is provided with protective device 5.Safety lifting platform also can comprise the master cock 3 with guar plate 2 interlocks, and master cock 3 is communicated with power control, jacking system 4 can adopt formations such as lifting motor, lifting motor driving system, elevating screw and support guide shaft, also fuel tank, motor can have been adopted, by motor-driven Hydraulic Pump, and the jacking system that the piston rod by pressure pipeline hydraulic ram of motion under pressure oil promotes constitutes constitutes.Lifting table 1 can adopt multiple shape according to the needs of daily production, as if use wider squarely at ordinary times, and guar plate 2 is located at respectively on four limits of lifting table 1, and the shaft center line of guar plate 2 is parallel to each limit of lifting table 1.

In order to can be good at making guar plate 2 its protective actions of performance, the part of avoiding stretching out lifting table along the guar plate rotation axis may not can rotate, people or property are produced the problem of pushing and damaging, protective device 5 can be as Fig. 4, and the hinge knot is provided with rebound on adjacent two guar plates, 2 one guar plates that are arranged on lifting table 1 each angle.Like this; when guar plate is had an effect; the rebound of hinge knot on guar plate 2 will rotate; avoided guar plate to stretch out the problem that the part of lifting table may not can rotate along rotation axis; realized the purpose of lifting table 1 each place, angle to people or property protection; equally; also can adopt as shown in Figure 2; between adjacent two guar plates 2 on lifting table 1 each angle, be the diagonal formula cooperation; perhaps as shown in Figure 3; on lifting table 1 each angle between adjacent two guar plates 2 hinge knot be provided with the transition guar plate; the transition guar plate intersects respectively around the shaft center line of the place's rotation of hinge knot and its shaft center line and adjacent two guar plates 2; shaft center line as the transition guar plate can equate with the angle of the shaft center line of adjacent two guar plates 2; these structures; can solve guar plate and not rotate, people or property are produced extruding and damage, thereby reach purpose people or property protection along the part that its rotation axis stretches out lifting table.
