Specific embodiment

To keep the purpose of this utility model, technical solution and advantage clearer, below by the technology to the utility model Scheme is described in detail.Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than comprehensively Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not before making creative work Obtained all other embodiment is put, the range that the utility model is protected is belonged to.

Embodiment:

As shown in Figure 1 and Figure 2, a kind of mechanical balance counterweight lifting ground well fixed point of the utility model stops check device, Including column 1, crane 2, well cover, lockable mechanism and the fixed point emergency stop operation mechanism 15 cooperated with the lockable mechanism, institute The column 1 stated is arranged along the depth direction of ground well, and the crane 2 is slidably matched with the column 1；The fixed point emergency stop behaviour Make mechanism 15 to be mounted at well cover, the lockable mechanism includes female lock section point and the male lock section with mother lock section distribution conjunction Point, the lock section female lock section Fen Hegong is separately mounted on crane 2 and column 1.A kind of machinery of the utility model is flat The counterweight lifting ground well fixed point that weighs stops check device, anxious by column 1, crane 2, well cover, lockable mechanism and fixed point The cooperation for stopping operating mechanism 15 etc., when elevating mechanism fall when ground, realize fixed point locking with can be convenient, greatly The earth improves security performance, reduces the generation of contingency.

Preferably, female lock section point includes the positioning sleeve 3 being mounted on crane 2, the public lock section point Including the locating rod fixed frame 4 being mounted on column 1, the locating rod fixed frame 4 is hollow and is combined with locating rod 6；Described determines Locating rod fixed frame 4 and the cooperation of positioning sleeve 3 are freely stretched out in position bar 6 one end, the other end be combined with resetting-mechanism and with it is described Emergency stop operation mechanism 15 is pinpointed to cooperate.

Preferably, the resetting-mechanism includes baffle and spring 5, the baffle plate setting is in the locating rod 6 outsides, the spring 5 is sleeved in locating rod 6 and both ends contact 4 inner wall of baffle and locating rod fixed frame respectively.It is worth note Meaning, one end that the locating rod 6 stretches out locating rod fixed frame 4 is to be generally lozenges, the port of the positioning sleeve 3 Outside corresponding lozenges is set；When ground well works completion, operator steps on pedal lock, the lifting of ground well by foot Mechanism moves down, and when being moved to the position apart from ground 300mm or so, passes through lozenges between locating rod 6 and positioning sleeve 3 Cooperation, so that the compressed spring 5 in locating rod fixed frame 4 of locating rod 6, which is moved backward, enters null when escaping 3 upper surface of positioning sleeve Cheng Shi, it is fixed that the spring 5 of compression pushes locating rod 6 to be advanced into the at this moment whole process realization of positioning sleeve 3 under the effect of elasticity Point location.Around ensuring after safety, fixed point emergency stop operation mechanism 15 is reused, locating rod 6 is eventually transferred to and to press backward Contracting spring 5 makes locating rod 6 be detached from the fixed point location limitation that positioning sleeve 3 eliminates ground well, finally falls ground well.

Preferably, the fixed point emergency stop operation mechanism 15 is connect with the locating rod 6 by wirerope 7.Steel Cord 7 has biggish intensity while having flexibility, and use is quite convenient.

Preferably, the fixed point emergency stop operation mechanism 15 includes fixed frame 13, lock 8 and operation handle 14, The fixed frame 13, lock 8 are fixedly mounted on well cover, and the operation handle 14 is hinged on well cover and is located at The top of lock 8；The wirerope 7 is connected to 13 top of fixed frame；It is provided in the lock 8 and freely stretches out lock 8 Lock tongue 10, the one end fits of the lock tongue 10 have a telescoping mechanism, and the other end is provided with the guide wheel 11 cooperated with wirerope 7；It is described Operation handle 14 and the telescoping mechanism cooperate.When specifically used, by the flexible of lock tongue 10, drive guide wheel 11 dynamic Make, to drive the movement with the wirerope 7 of guide wheel 11, and then realizes the movement of locating rod 6, realize locking and unlock.

Preferably, the telescoping mechanism includes the sliding bar 16 for freely passing through lock 8 up and down, the sliding bar 16 Upper end is hinged in operation handle 14；The first wedge block 17 is arranged on the sliding bar 16, in the lock tongue 10 End is provided with the second wedge block 18 with first wedge block 17 cooperation.

Preferably, being provided with steel rope guide sleeve 9 in the lower part of the fixed frame 13, the wirerope 7 is worn Fixed-link is in 13 top of fixed frame, the guide wheel 11 and the wirerope 7 cooperation and position after crossing the steel rope guide sleeve 9 Between steel rope guide sleeve 9 and the fixing end of wirerope 7.When in use, operator passes through the up and down action of operation handle 14, It drives sliding bar 16 to move up and down, so that being relatively moved between the first wedge block 17 and the second wedge block 18, realizes to lock The promotion of tongue 10 to change the position of guide wheel 11, and then changes the upper and lower displacement of wirerope 7, the final lock for realizing locating rod 6 Only, it unlocks.The effect of steel rope guide sleeve 9 plays the role of guiding, so that in entire action process, steel rope guide sleeve 9 Wirerope 7 below can only act along vertical direction.

Preferably, the fixed frame 13 is bolted to connection on well cover.It, can be with after designing in this way It easily disassembles and installs, adapts to different demands, if desired the displacement range of wirerope 7 is larger, then can say fixed frame 13 are mounted on closer to the position of lock 8, and vice versa.

Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to In this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation Or replacement, it should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with the power Subject to the protection scope that benefit requires.
