Abstract
The utility model provides a lifting hook of adjustable shield structure machine part gesture in shield structure machine hoist and mount process that goes into well which characterized in that: a screw rod is vertically and fixedly arranged on the mounting frame, a top fastening nut is arranged at the connecting position of the screw rod and the upper part of the mounting frame, a bottom fastening nut is arranged at the connecting position of the screw rod and the lower part of the mounting frame, and a hanging ring connected with a steel cable is arranged at the top of the screw rod; and a preformed hole for connecting a bolt is formed in the mounting frame. The utility model has the advantages of being simple in structure and convenient in operation, come adjustment lifting hook length through adjustment top fastening nut and bottom fastening nut to adjust the lower well gesture of shield structure machine, avoid the deviation of the bolt hole site between shield structure machine part, with reach and be connected with the accuracy of other shield structure machine parts in the pit, improve the shield and construct packaging efficiency.
Description
Technical field
The utility model belongs to the realm of building construction, and particularly a kind of shield machine is gone into the well the suspension hook of adjustable shield machine component pose in hoisting process.
Background technology
Current each big city is all being built or is being planned to build metro project, the preferred unit that shield machine Shi Ge unit in charge of construction tunnels as transit tunnel, but shield machine build is comparatively large, goes into the well and to go out well very difficult, and at substantial manpower, financial resources, material resources, slightly problem will affect the duration.How to improve shield machine to go into the well and installation effectiveness has great importance to subway construction.
When lifting shield machine, traditional hook is fixing parts, can not adjust length.When lifting shield machine parts, position, shield structure hole is relatively stricter to the Gesture of shield structure parts in down-hole, if attitude misalignment is comparatively large, the tie bolt of adjacent shield machine parts can be caused to install smoothly.In addition, shield machine part dimension and weight are all comparatively large, shaft bottom track carries out manual deviation rectification to it and regulates very difficult.
As far as possible traditional installation method ensures before lifting by crane that hanger position is accurate, accurate, but due to the difference that the uneven and temperature difference of rope stress deformation in the size of lifting rope and suspension hook and lifting process causes rope lengths to change, exist certain for overgauge under causing shield machine behind shaft bottom and between adjacent component, thus cause assembly and connection difficulty.
Summary of the invention
The purpose of this utility model is exactly solve the weak point in above-mentioned orthodox method, the suspension hook that a kind of shield machine goes into the well adjustable shield machine component pose in hoisting process is provided, the deviation that this Suspension hook structure is simple, easy to operate, can realize fine tune to shield machine component pose, avoid spiro keyhole position between shield machine parts, improves shield structure packaging efficiency.
As above conceive, the technical solution of the utility model is: a kind of shield machine is gone into the well the suspension hook of adjustable shield machine component pose in hoisting process, it is characterized in that: on erecting frame, be vertically fixedly mounted with a screw rod, the connection location on screw rod and erecting frame top installs top clamp nut, the connection location of screw rod and erecting frame bottom installs bottom clamp nut, and screw tip is shaped with the suspension ring connecting cable wire; Described erecting frame has the preformed hole for tie bolt.
Above-mentioned erecting frame is " n " shape.
The utility model has following advantage and good effect:
1, the utility model is by adjustment top clamp nut and bottom clamp nut, adjust hook length, thus adjust the attitude of going into the well of shield machine, avoid the deviation of spiro keyhole position between shield machine parts, to reach accurate connection the with other shield machine parts of down-hole, improve shield structure packaging efficiency.
2, the utility model structure is simple, easy to operate.
Accompanying drawing explanation
Fig. 1 is the utility model integral structure schematic diagram;
Fig. 2 shield machine parts hangers schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1: a kind of shield machine is gone into the well the suspension hook of adjustable shield machine component pose in hoisting process, " n " shape erecting frame 6 is vertically fixedly mounted with a screw rod 4, the connection location on screw rod and erecting frame top installs top clamp nut 2, the connection location of screw rod and erecting frame bottom installs bottom clamp nut 3, and screw tip is shaped with the suspension ring 1 connecting cable wire; Described erecting frame has the preformed hole 5 for tie bolt.
As shown in Figure 2, the position of shield machine parts hanger 7,8,9,10 is accomplished accurately as far as possible, but in assembling and mounting process, often there is certain error, cause shield machine lifting part more difficult with the connection between underground component, the link bolt hole position misalignment between adjacent component.And shield machine parts are very clumsy, carry out the pose adjustment effect that wastes time and energy in shaft bottom by artificial method poor, therefore can regulating hook according to error condition, to reduce attitude dislocation, providing condition for connecting shield machine smoothly.
Suppose shield machine 9,10 places right half part on the low side, the adjustable suspension ring be connected on 9,10 hangers can be adjusted simultaneously, make shield machine component right half part increase by a small margin, until position suitable.
First reduce suspension ring, make lifting rope be in the state of not stressing to regulate suspension hook, with spanner, top clamp nut 2 is upwards unscrewed, bottom clamp nut 3 is up screwed, thus slightly reduce suspension hook length, then tighten top clamp nut 2.Slow lifting hook, until shield machine parts are lifted completely, owing to slightly reducing the length of the suspension hook of 9,10 positions, make shield machine right part be improved, have adjusted the attitude of shield machine, until shield machine component pose meets installation requirement.
The utility model handling ease, simple to operate, among a small circle in effectively can adjust the attitude of shield machine parts, to meet requirement that equipment installs, to improve installation effectiveness.
