Description
Technical field
The utility model relates to a kind of fence gate, and particularly a kind of building hoist is two opens fence gate.
Background technology
Building hoist is made up of a few parts such as car, driver train, standard knot, attached wall, chassis, fence and electric systems, is the manned cargo-carrying construction machinery and equipment often used in building.Building hoist usually coordinates with tower crane and carries out construction operation, due to aloft work, so have very high requirement to the car door of car and the fence gate of fence, avoids because of car door or the not firm and security hidden trouble that causes of fence gate closedown.
Existing building hoist fence gate has single open-door and double door two kinds of forms.Single open-door for slide up and down installation on fence, and its unlatching realizing door by the cooperation of pulley, steel rope and counterweight, with closed, exists complex structure, drawback that cost is high; Double door is the door-plate that two fans are split, although itself and single open-door structure compared are comparatively simple, it is when locking, needs to utilize keeper by two fan door locks, in order to ensure the steadiness of locking, keeper needs certain weight, not only adds the manufacturing cost of fence but also be unfavorable for the locking of fence gate, in addition, double door fence gate is under the state of non-locking, door-plate can freely swing, and the open and close of door-plate are unstable, shortens the service life of door-plate in the situation of long-term collision next time.
Summary of the invention
The purpose of this utility model is to provide that a kind of scientific structure design is reasonable, structure is simple, productive costs is low, the building hoist of long service life is two opens fence gate.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of building hoist is two opens fence gate, comprise door frame and door-plate, split in described door frame and door-plate is installed, it is characterized in that: also comprise door lock mechanism and door-plate fixed mechanism, described door lock mechanism is by latch hook, square tube, force application rod, spring and force wheel are formed, described square tube is rotated by the bearing pin that its both ends are fixed and is installed on the upper portion door framework of door-plate, the latch hook of hook door-plate is symmetrically installed with at the middle part of square tube, at the end rear vertical of square bar, force application rod is installed, the end of force application rod is provided with the force paralleling setting with it take turns, described spring is vertically installed between force application rod and the upper crossbearer of door frame, be provided with an adapter plate in the lower end, middle part of described square tube, be provided with door-plate fixed mechanism in the middle part of the lower end of this adapter plate, described door-plate fixed mechanism is the buffering blob of viscose of an inner setting-in Nd-Fe-B permanent magnetic block.
And, described door-plate is provided with photoelectric switch.
And, the vertical stand of door frame both sides is symmetrically installed with gear door buffing pad, gear door buffing pad is fixed with Nd-Fe-B permanent magnetic block.
Advantage of the present utility model and beneficial effect are:
1. this building hoist is two opens fence gate, by increasing door lock mechanism and door-plate fixed mechanism two opening on fence gate, make fence gate be locked in reduce manufacturing cost while more safe and reliable.When car upward movement, force application rod can upwards lift by car, utilizes the principle of lever, and the latch hook of square tube interlock can live door-plate by downward snap close, completes the locking action of door-plate; When car moves downward, force application rod can press downwards by car, utilizes lever principle equally, and the snap close of square tube interlock can upwards lift, and completes the breakdown action of door-plate.Door-plate fixed mechanism, the i.e. setting of Nd-Fe-B permanent magnetic block, can adsorb door-plate, avoids it to swing back and forth, the problem of reduction of service life.
2. this building hoist is two opens fence gate, and by installing photoelectric switch on door-plate, this photoelectric switch is connected with car in use, realization only under the state of fence gate locking car can work, otherwise car cannot start, and ensure that construction safety.
3. this building hoist is two opens fence gate, installs Nd-Fe-B permanent magnetic block, make fence gate under the state of opening, door-plate also can be kept to fix by symmetrical in the vertical stand of door frame both sides.
4. the utility model scientific structure design is reasonable, has the advantage that structure is simple, productive costs is low, long service life, locking are firm, safe and reliable, is that a kind of building hoist pair with higher innovation opens fence gate.

Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A kind of building hoist is two opens fence gate, comprise door frame and door-plate 3, split in described door frame and door-plate is installed, its innovation is: also comprise door lock mechanism and door-plate fixed mechanism, described door lock mechanism is by latch hook 7, square tube 4, force application rod 13, spring 12 and force wheel 14 are formed, described square tube is rotated by the bearing pin 11 that its both ends are fixed and is installed on the upper portion door framework of door-plate, the latch hook of hook door-plate is symmetrically installed with at the middle part of square tube, at the end rear vertical of square bar, force application rod is installed, the end of force application rod is provided with the force paralleling setting with it take turns, described spring is vertically installed between force application rod and the upper crossbearer 2 of door frame, in the lower end, middle part of described square tube, one adapter plate 5 is installed, door-plate fixed mechanism is installed in the middle part of the lower end of this adapter plate, described door-plate fixed mechanism is the buffering blob of viscose 6 of an inner setting-in Nd-Fe-B permanent magnetic block, avoid fence gate contact with the direct of Nd-Fe-B permanent magnetic block by Nd-Fe-B permanent magnetic block being inlaid on buffering blob of viscose, both having reduced the sound sent when fence gate and Nd-Fe-B permanent magnetic block collide, and having ensured that again Nd-Fe-B permanent magnetic block was not damaged when colliding for a long time.
Described door-plate is provided with photoelectric switch 10.
The vertical stand 1 of door frame both sides is symmetrically installed with gear door buffing pad 9 setting up and down, gear door buffing pad is fixed with Nd-Fe-B permanent magnetic block 8.
By increasing door lock mechanism and door-plate fixed mechanism two opening on fence gate, make fence gate be locked in reduce while manufacturing cost more safe and reliable.When car upward movement, force application rod can upwards lift by car, utilizes the principle of lever, and the latch hook of square tube interlock can live door-plate by downward snap close, completes the locking action of door-plate; When car moves downward, force application rod can press downwards by car, utilizes lever principle equally, and the snap close of square tube interlock can upwards lift, and completes the breakdown action of door-plate.Door-plate fixed mechanism, the i.e. setting of Nd-Fe-B permanent magnetic block, can adsorb door-plate, avoids it to swing back and forth, the problem of reduction of service life.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
