Description
Technical field
The utility model belongs to Architectural Equipment technical field, is specifically related to a kind of precast concrete trench cover lifting device.
Background technology
Precast concrete trench cover is a kind of Architectural Equipment being widely used in town road, sending the multiple places such as power transformation cable trough, garden furniture, residential quarters, school and stadiums.Existing precast concrete trench cover is generally complete lifting operation by promoting the reinforcing bar draw ring be fixedly installed on above trench cover, therefore, there is that cost is high, profile unsightly, facility is of poor quality, use is inconvenient and the inflexible technical problem of operation.
Summary of the invention
The purpose of this utility model be high, the profile of cost that exists of the reinforcing bar draw ring solving existing lifting precast concrete trench cover unsightly, facility is of poor quality, use is inconvenient and the inflexible technical problem of operation, provides a kind of precast concrete trench cover lifting device.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of precast concrete trench cover lifting device, comprise fixture, handle and protective cap, described fixture is made up of circular steel jacketing and nut, and nut is located at the bottom of circular steel jacketing inner chamber, and protective cap is located at the top of circular steel jacketing; Described handle is made up of steel pipe handle and bolt, and the upper end of bolt is fixedly connected with the centre of steel pipe handle outer wall.
The utility model adopts technique scheme, be arranged in precast concrete trench cover by pre-buried for one group of fixture, when needing to promote precast concrete trench cover, one group of handle is screwed in fixture, precast concrete trench cover can be mentioned by the steel pipe handle promoting handle, then further work is completed, after work completes, by the steel pipe handle promoting handle, the recovery of precast concrete trench cover is covered on trench, to back-out handle, then one group of protective cap is covered the top at circular steel jacketing respectively, handle can have enough to meet the need use, efficiently cheap, the cost that the reinforcing bar draw ring solving existing lifting precast concrete trench cover exists is high, profile unsightly, facility is of poor quality, use inconvenient and the inflexible technical problem of operation.Therefore, compared with background technology, the utility model have with low cost, good looking appearance, facility quality are good, easy to use and the advantage of operating flexibility, and assembly raw material can be gathered materials on the spot from job site completely, secondary operations amount is few, and practicality is high, and popularizing application prospect is wide.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model fixture;
Fig. 3 is the structural representation of the utility model handle.
Embodiment
As shown in Figures 1 to 3, a kind of precast concrete trench cover lifting device in the present embodiment, comprise fixture, handle and protective cap 1, described fixture is made up of circular steel jacketing 2 and nut 3, nut 3 is located at the bottom of circular steel jacketing 2 inner chamber, and protective cap 1 is located at the top of circular steel jacketing 2; Described handle is made up of steel pipe handle 4 and bolt 5, and the upper end of bolt 5 is fixedly connected with the centre of steel pipe handle 4 outer wall.
The course of work of the present utility model is:
1) before precast concrete trench cover casting concrete, by one group of fixture pre-buried both sides being set to precast concrete trench cover bar-mat reinforcement respectively, and the bar-mat reinforcement of the outer wall of fixture circular steel jacketing 2 and precast concrete trench cover is welded and fixed, casting concrete again after fixation, for the hole of protection fixture circular steel jacketing 2 is neatly unobstructed, can one group of protective cap 1 be covered on circular steel jacketing 2 top respectively before building;
2) when needing lifting precast concrete trench cover to carry out operation, open protective cap 1, the bolt 5 of one group of handle is stretched in the circular steel jacketing 2 of two fixtures respectively, and bolt 5 and nut 3 are tightened, after handle and fixture are tightened and are fixed, precast concrete trench cover can be promoted by the steel pipe handle 4 promoting one group of handle, then complete further work;
3) after work completes, cover by the steel pipe handle 4 promoting one group of handle on trench by the recovery of precast concrete trench cover, handle of back-outing, then covers on the top of circular steel jacketing 2 respectively by one group of protective cap 1.
