Abstract
The utility model provides a mesh-hole type counterweight protection screen which comprises a frame main body and a mesh sheet, the frame main body is formed through the welding of a steel plate bending piece or a profile, an upper beam and a lower beam; the beams are connected with each other in a welding manner, the mesh sheet is arranged on the frame main body, reinforcing pieces are fixed on the frame main body by a common steel plate in a welding manner, transverse reinforcing pieces are arranged in the frame main body, and at least two transverse reinforcing pieces are arranged in the frame main body. Due to the designed mesh-hole type counterweight protection screen, an operator can inspect the states of a buffer, a safety loop switch and other materials of a counterweight system in a visualized manner without disassembling a counterweight protection frame when overhauling a bottom pit; moreover, the mesh-hole type counterweight protection screen can protect the operator, thereby improving the safety performance of the whole overhauling process.
Description
Technical field
The utility model relates to manufacturing industry of the lift, particularly a kind of mesh-type counterweight protection screen.
Background technology
Existing elevator device generally comprises car and counterweight system; for counterweight system is shielded; consider repair and maintenance personnel's personal safety simultaneously; according to relevant criterion counterweight protection framework must be set; existing protection framework mostly is the bending member of cold drawing or zincing steel sheet; install comparatively complicated; whole cost is higher; and after the assembling, no through hole, so operating personal is when pit overhauls; can't be intuitively efficiently to the energy disperser of counterweight system; the state of safety return circuit switch and other materials is checked; overhaul again after counterweight must being protected the framework dismounting, the operation relative complex, labor cost is higher.
The utility model content
At above problem; the utility model is by a kind of mesh-type counterweight protection screen of design; make operating personal when pit overhauls; need not to dismantle counterweight protection framework; can be intuitively to the energy disperser of counterweight system; the state of safety return circuit switch and other materials is checked; for reaching this purpose; the utility model provides a kind of mesh-type counterweight protection screen; described mesh-type counterweight protection screen comprises chassis body and net sheet; described chassis body is assigned in underbeam by steel plate bending part or section bar and is welded to form; connect by welding between the described beam, described net sheet is arranged on the chassis body, is provided with horizontal reinforcement in the described chassis body.
As further improvement of the utility model, be provided with at least two horizontal reinforcements in the described chassis body, reinforcement passes through welding by general steel plate, be fixed on the chassis body, in order to increase the intensity of general frame, at least two horizontal reinforcements can be set in chassis body to strengthen the intensity of general frame.
The utility model is by a kind of mesh-type counterweight protection screen of design; make operating personal when pit overhauls; need not to dismantle counterweight protection framework; can be intuitively the state of energy disperser, safety return circuit switch and other materials of counterweight system be checked; and it can shield to operating personal, has improved the safety of whole maintenance process.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Member among the figure is:
1, chassis body; 2, net sheet; 3, reinforcement;
The specific embodiment
Below in conjunction with drawings and Examples utility model is described in detail:
The utility model makes operating personal when pit overhauls by a kind of mesh-type counterweight protection screen of design, need not to dismantle counterweight protection framework, can be intuitively the state of energy disperser, safety return circuit switch and other materials of counterweight system be checked.
The utility model provides a kind of mesh-type counterweight protection screen as shown in Figure 1; described mesh-type counterweight protection screen comprises chassis body 1 and net sheet 2; described chassis body 1 is assigned in underbeam by steel plate bending part or section bar and is welded to form; connect by welding between the described beam; described net sheet 2 is arranged on the chassis body 1; be provided with horizontal reinforcement 3 in the described chassis body 1; be provided with at least two horizontal reinforcements 3 in the described chassis body 1; reinforcement 3 passes through welding by general steel plate; be fixed on the chassis body 1; in order to increase the intensity of general frame 1, at least two horizontal reinforcements 3 can be set in chassis body 1 to strengthen the intensity of general frame 1.
The utility model is by a kind of mesh-type counterweight protection screen of design; make operating personal when pit overhauls; need not to dismantle counterweight protection framework; can be intuitively the state of energy disperser, safety return circuit switch and other materials of counterweight system be checked; and it can shield to operating personal, has improved the safety of whole maintenance process.
The above; it only is preferred embodiment of the present utility model; be not to be the restriction of the utility model being made any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that technical spirit of the present utility model is done.
