Description
Technical field:
The utility model relates to a kind of transfer crane railing door with hidden magnetosensitive safety switch.
Background technology:
At present; safety switch on the transfer crane divider gate all is made up of the travel switch of physical construction; do not meet the condition of trouble free service as hoisting crane; hoisting crane is with regard to cisco unity malfunction; protected user's life security to a certain extent, but because transfer crane places open-air work mostly, so the very easily corrosion under mal-conditions such as wind and weather of divider gate upper stroke switch contact; thereby cause the malfunctioning of system, bring hidden danger to safety.
Summary of the invention:
The purpose of this utility model is in order to overcome above deficiency, and a kind of transfer crane railing door of band hidden magnetosensitive safety switch simple in structure, with low cost, easy for installation is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of transfer crane railing door with hidden magnetosensitive safety switch; comprise the first doorframe bar; the second doorframe bar; door leaf; one side of door leaf links to each other by at least two movable blinds with the second doorframe bar; the first doorframe bar middle and upper part is provided with first keeper; the first doorframe bar middle and lower part is provided with dried spring and dried spring lead-in wire; dried spring lead-in wire is drawn from the bottom of dried spring; dried spring and dried spring lead-in wire periphery are provided with the epoxy resin protective cover; another inboard, side middle and upper part of door leaf is provided with second keeper; and second keeper is corresponding with first keeper that the first doorframe bar middle and upper part is provided with; be provided with permanent magnet in the steel pipe of another side middle and lower part of door leaf; the permanent magnet periphery also is surrounded by the epoxy resin protective cover; permanent magnet is provided with dried spring with the first doorframe bar middle and lower part and dried spring lead-in wire is corresponding, and another outside, side bottom of door leaf is provided with door shield.
The utility model compared with prior art has the following advantages: adopt the magnetosensitive switch; and the outside all has epoxy resin protecting; play whole leak free effects; therefore the contact on the divider gate is not corroded by extraneous rainwater, dust storm, soda acid gas; the utmost point is not easy malfunctioning; and total system all with the flexible material sealing, has effectively improved the shock resistance of system, thereby has strengthened the reliability of system greatly.
Description of drawings:
Structural representation when Fig. 1 closes for the utility model;
Structural representation when Fig. 2 opens for the utility model;
Number in the figure: the 1-first doorframe bar, the 2-second doorframe bar, 3-door leaf, the movable blinds of 4-, 5-first keeper, the dried spring of 6-, the dried spring lead-in wire of 7-, 8-protective cover, 9-second keeper, 10-permanent magnet, 11-door shield.
The specific embodiment:
In order to deepen understanding of the present utility model, the utility model is described in further detail below in conjunction with embodiment and accompanying drawing, and this embodiment only is used to explain the utility model, does not constitute the qualification to the utility model protection domain.
As Fig. 1; Fig. 2 shows a kind of embodiment of the transfer crane railing door of the utility model band hidden magnetosensitive safety switch; comprise the first doorframe bar 1; the second doorframe bar 2; door leaf 3; one side of door leaf 3 links to each other by at least two movable blinds 4 with the second doorframe bar 2; make things convenient for door leaf 3 to open or close; the first doorframe bar, 1 middle and upper part is provided with first keeper 5; the first doorframe bar, 1 middle and lower part is provided with dried spring 6 and dried spring lead-in wire 7; dried spring lead-in wire 7 is drawn from the bottom of dried spring 6; can prevent that like this rainwater from can enter in the dried spring 6 along dried spring lead-in wire 7; further protected dried spring 6; dried spring 6 and dried spring 7 peripheries that go between are provided with epoxy resin protective cover 8; with dried spring 6 and all sealings of dried spring lead-in wire 7; another inboard, side middle and upper part of door leaf 3 is provided with second keeper 9; and second keeper 9 is corresponding with first keeper 5 that the first doorframe bar, 1 middle and upper part is provided with; second keeper 9 can rotate; be provided with permanent magnet 10 in the steel pipe of door leaf 3 another side middle and lower parts; permanent magnet 10 peripheries also are surrounded by epoxy resin protective cover 8; this epoxy resin protective cover 8 is a flexible material; can not only play the leak free effect; also effectively improved the shock resistance of system; thereby strengthened the reliability of system greatly; permanent magnet 10 and the first doorframe bar, 1 middle and lower part are provided with dried spring 6 and dried spring and go between 7 corresponding; another outside, side bottom of door leaf 3 is provided with door shield 11; when shutting door leaf 3, another side of door leaf 3 just in time flushes with the second doorframe bar 2.
As shown in Figure 2; when the railing door is opened; be that permanent magnet 10 in the door leaf 3 is during away from the dry-reed tube 6 on the first doorframe bar 1; often open the contact of dry-reed tube 6; thereby disconnect the hoisting crane power supply; hoisting crane just can not normally move; as shown in Figure 1; have only when the railing door is shut; the contact of promptly dried spring 6 is subjected to the effect of permanent magnet 10 and during adhesive; just can make the power connection of hoisting crane, carry out normal operation, play good safety guard-safeguard effect; and owing to the dried spring 6 and the permanent magnet 10 of magnetosensitive switch is separately positioned in the steel pipe of the first doorframe bar 1 and door leaf 3; have good protective with disguised, be not subject to the external force effect and produce misoperation, further strengthened automatically controlled reliability.
