Abstract
The utility model relates to a vertical construction well lid door opening device, it includes and derrick (1) is equipped with well lid door winch (4) on two platforms (2) of derrick (1), and the well head of derrick (1) bottom is equipped with closure plate (10), and wellhole in closure plate (10) is equipped with dimidiate well lid door (8), its characterized in that: set up one hinge seat (9), one lift bar (11) are connected at hinge seat middle part, and lift bar (11) upper end is connected with haulage rope (5), the inboard of every well lid door (8) articulates one bracing piece (7) respectively, and the other end difference symmetric connection of every bracing piece (7) is on hinge seat (9). Be equipped with haulage rope (5) in the well lid door winch (4), haulage rope (5) are connected with lift bar (11) through pulley (3) on derrick upper portion, the beneficial effect of the utility model: the utility model provides a well lid door opening device compares with traditional opening device, and the fault rate is low, safe and reliable.
Description
technical field:
The utility model belongs to pit mining apparatus field, particularly a kind of shaft construction trapdoor opening device.
background technology:
Between coal mine shaft lining mine construction stage, as shown in Figure 1, all use the upper and lower personnel of well-bucket 13, promote dregs and spoil, and transfer and lifting construction materials.In order to ensure the safety of underground construction personnel, all at aboveground mouth, closure plate 10 is installed, and at well-bucket 13 by place, installs trapdoor 8, when well-bucket is upper and lower run through time open.When well-bucket is out of service, trapdoor is closed, anti-falling stop thing.Trapdoor 8 realizes opening and closing by haulage cable 5 up-and-down movement be wrapped on traction winch 4, and traction winch has special messenger to control the rotation of positive and negative both direction, realizes the Kai Heguan of trapdoor.The many employings of switch of tradition trapdoor are installed " bow 8a " on trapdoor, and " bow " installs steel rope, and the steel rope on " bow " is connected with traction winch lay winding wire ropes again.Due to " bow " that trapdoor is arranged, make trapdoor complex structure, weight comparatively large, two other " bow " all wants connecting steel wire ropes respectively, in use easily steel rope abrasion phenomenon of rupture occurs, bring larger hidden danger to safety in production.
summary of the invention:
The purpose of this utility model is exactly to overcome the poor defect of existing trapdoor complex structure, safety, and a kind of shaft construction trapdoor opening device provided.
The technical solution adopted in the utility model is as follows:
Shaft construction trapdoor opening device, its bag
Derrick, two platforms of derrick are provided with trapdoor winch, closure plate is provided with bottom derrick, the wellhole of closure plate is provided with the trapdoor split, be provided with hauling rope in trapdoor winch, hauling rope is connected with the trapdoor split by the pulley of upper derrick, it is characterized in that: arrange a hinge seat, connect a lifting arm in the middle part of hinge seat, lifting arm upper end is connected with hauling rope; The inner side of each trapdoor is a hinged strut bar respectively, and the other end of each strut bar respectively symmetry is connected on hinge seat.
On the basis of technique scheme, can have following further technical scheme: the girder steel of the wellhole side of closure plate connects a guide pipe, lifting arm is that slide-and-guide coordinates through guide pipe.
The beneficial effects of the utility model: the trapdoor opening device that the utility model provides compared with traditional opening device, failure rate is low, safe and reliable.
accompanying drawing illustrates:
Fig. 1 is this existing trapdoor opening structure schematic diagram;
Fig. 2 is trapdoor opening device opening schematic diagram of the present utility model;
Fig. 3 is trapdoor opening device closed condition schematic diagram of the present utility model;
Fig. 4 is the guide pipe front view in Fig. 2, Fig. 3;
Fig. 5 is the birds-eye view of Fig. 4;
Fig. 6 is the A portion enlarged drawing of Fig. 2.
detailed description of the invention:
As shown in Fig. 2, Fig. 3 and Fig. 6, a kind of shaft construction trapdoor opening device that the utility model provides, its bag derrick 1, two platforms 2 of derrick 1 are provided with trapdoor winch 4 and pulley 3, well head place bottom derrick 1 is provided with closure plate 10, the wellhole of closure plate 10 is provided with the trapdoor 8 split, the steel rope 5(hauling rope be provided with in trapdoor winch 4) and walk around the pulley 3 of upper derrick.
Arrange a hinge seat 9, an affixed lifting arm 11 in the middle part of hinge seat, lifting arm 11 upper end is provided with steel rope coupling link 12 and is connected with hauling rope 5; A respectively hinged strut bar 7 on one side of the inner side of each trapdoor 8, the other end of each strut bar 7 respectively symmetry is connected on hinge seat 9.
The girder steel 10a of the wellhole side of closure plate 10 connects a guide pipe 6, and lifting arm 11 coordinates in slide-and-guide through guide pipe 6.
As shown in Figure 4, Figure 5, guide pipe about 6 welds two leg-of-mutton adapter plate 6a, and adapter plate 6a is welded on fixed board 6b, and fixed board 6b bolt is connected on girder steel 10a.
Working process of the present utility model is as follows: as shown in Figure 2, trapdoor winch 4 draws high lifting arm 11 by steel rope 5 and moves up, strut bar 7 hinged on hinge seat 9 promotes trapdoor 8 and upwards overturns, it is limited when hinge seat 9 touches guide pipe 6, trapdoor winch 4 stops operating, and now trapdoor 8 is in open mode.
As shown in Figure 3, when trapdoor winch 4 loosens steel rope 5, lifting arm 11 is moved down, hinge seat 9 drives trapdoor 8 to overturn downwards by strut bar 7, when trapdoor 8 close up be in closedown time, trapdoor winch 4 stops operating, and lifting arm 11, hinge seat 9 and strut bar 7 are all in below well head.
