Abstract
The utility model discloses a safety door of discharge platform for well headframe construction lifter, which comprises a suspension cage and a safety door, the mechanical interlocking device is mainly composed of a safety door locking block, a balance locking block, a push rod, a collision iron, a balance weight, and a lever, the safety door locking block and the balance locking block are movably connected with the lever, the lever is connected fixedly with the push rod, the push rod is connected fixedly with the spring and the slide locking block, the slide locking block is movably connected with the collision iron. The utility model has the advantages of simple structure, low price and good reliability, the safety door is connected with the suspension cage of the lifter, only when the suspension cage runs to the material discharge platform, the safety door on the device can be opened by operator, thereby preventing the lifter from being opened by operator or other persons randomly to result in unnecessary personal injury, and also improving safety performance of safety door.
Description
Technical field
The utility model relates to a kind of safety device of building operation, especially a kind of derrick building hoist discharging platform safety door.
Background technology
Derrick is a requisite vertical transportation machinery in the building operation, and floor discharging platform safety door is the significant points of derrick job safety protection.Derrick building hoist discharging platform safety door in the present construction site, usually by opening and closing manually, its shortcoming is: in easy clamshell doors of floor gap device, this safety door is not connected with the cage of elevator, the staff arbitrarily opens turnover, stretches out one's hand toward interior probe, has great potential safety hazard; Though the part safety door adopts the automated installation of dynamo-electric combination control or full mechanical control, realized opening and closing automatically of safety door, but these apparatus structures are complicated, reliability is relatively poor, cost is high, and to often safeguard, but under the harsh environment of building ground, break down easily and lose the safety precaution effect.
The utility model content
The purpose of this utility model provide a kind of simple in structure, cost is lower, the derrick building hoist discharging platform safety door of the full mechanical control of good reliability, this safety door is connected with the cage of elevator, have only when cage runs to the discharging position of platform, safety door on the device could be opened by the staff, avoid elevator staff or other staff in motion process arbitrarily to open, cause the generation of unnecessary personal injury accident, improved the usage safety performance of safety door.
For solving the problems of the technologies described above, the technical solution of the utility model is:
This derrick building hoist discharging platform safety door comprises: cage, safety door, mechanical interlocking device mainly by safety door fixture block, counterweight fixture block, push rod, bump iron, clump weight, connecting rod and form; Safety door fixture block, counterweight fixture block and connecting rod flexibly connect, and connecting rod is captiveed joint with push rod.
Push rod is captiveed joint with spring, slip fixture block, the slip fixture block with bump ironwork and be dynamically connected.
The beneficial effects of the utility model:
The utility model be a kind of simple in structure, cost is lower, the full mechanical control derrick building hoist discharging platform safety door of good reliability, this safety door is connected with the cage of elevator, have only when cage runs to the discharging position of platform, safety door on the device could be opened by the staff, avoid elevator staff or other staff in motion process arbitrarily to open the generation that causes unnecessary personal injury accident, improved the usage safety performance of safety door.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Mechanical interlocking device front view when Fig. 2 is the safety door closed condition.
Mechanical interlocking device front view when Fig. 3 is the safety door opening.
Fig. 4 is the birds-eye view of mechanical interlocking device.
Fig. 5 is the left view of mechanical interlocking device.
Shown in the figure:
The 1-safety door, 2-safety door fixture block, 3-counterweight fixture block, the 4-push rod, 5-bumps iron, 6-clump weight, 7-mechanical interlocking device, 8-connecting rod, 9-spring, 10-slip fixture block.
The specific embodiment:
According to Fig. 1-shown in Figure 5, this derrick building hoist discharging platform safety door comprises: cage, safety door 1, mechanical interlocking device 7.
This safety door mechanism has adopted mechanical interlocking device 7, have only when cage runs to the discharging position of platform, safety door 1 on the device could be opened by the staff, avoid elevator staff or other staff in motion process arbitrarily to open the generation that causes unnecessary personal injury accident, improved the usage safety performance of common safety door.
This device mainly is to finish scheme by clump weight 6 and safety door 1 both cooperations, when cage arrival floor height, bump slip fixture block 10 on the iron 5 collision push rods 4 in the cage, collision push rod 4 has promoted counterweight fixture block 3 by spring 9, at this moment force safety door fixture block 2 to break away from safety door 1, this moment, the staff can arrive certain altitude by manual unlocking safety door 1, clump weight 6 is toward lower slider, counterweight fixture block 3 is a unidirectional pendulous device, can block clump weight 6 when clump weight 6 is run into counterweight fixture block 3, this moment, safety door was in opening.
If start cage, push rod 4 in the device has broken away from and has bumped iron 5 in the cage, spring 9 effects in the push rod 4 make counterweight fixture block 3 break away from clump weight 6, because weight ratio clump weight 6 weights of safety door 1, so gliding automatically, safety door 1 drives clump weight 6 risings, when safety door 1 bottom that glides, make safety door fixture block 2 block, this moment, safety door 1 was in closed condition.
