Detailed Description
The present application is described in further detail below with reference to the attached drawings.
The embodiment of the application discloses foundation ditch faces frontier defense guardrail convenient to remove. Referring to fig. 1, including fixing base 1, fixing base 1 is the cuboid form setting, referring to fig. 2, four fixed screw 17 have all been seted up with four angle departments to one side that fixing base 1 kept away from ground, and fixing screw 18 is worn to be equipped with by equal spiral on four fixed screw 17, and fixing screw 18's axis extends the setting along the direction of height, and fixing screw 18 extends to the foundation ditch and faces inside the limit. The fixing screw 18 is connected with the fixing screw hole 17 in a threaded manner and then extends to the inside of the edge of the foundation pit, so that the fixing seat 1 is more stable on the edge of the foundation pit.
Referring to fig. 1, a splicing column 2 is fixedly mounted at the center of one side of a fixing seat 1 far away from the edge of a foundation pit, splicing grooves 3 which are the same in size and opposite in direction are formed in two opposite side faces of the splicing column 2 perpendicular to a long axis of the fixing seat 1, and guard rails 4 are movably spliced between the two splicing grooves 3 opposite to the two splicing columns 2. The protective guard 4 plays a role in protection and isolation, and the insertion column 2 is in insertion fit with the insertion groove 3, so that the fixing seat 1 and the insertion column 2 are more flexibly mounted on the edge of the foundation pit and are convenient to mount and dismount the protective guard 4.
Two inclined supporting columns 13 are fixedly mounted on two side edges of the fixing seat 1, which are located on the insertion column 2, one ends of the inclined supporting columns 13 are fixedly connected with the fixing seat 1, and the other ends of the inclined supporting columns are fixedly connected with two side edges of the insertion column 2, which are not provided with the insertion groove 3. The inclined support column 13 makes the state of the inserting column 2 on the fixed seat 1 more stable.
The guard rail 4 is provided with a plurality of observation holes 14. The observation holes 14 are formed, so that peripheral construction personnel can effectively observe the environment inside the foundation pit, the observation holes 14 reduce the wind resistance of the protective guard 4, and the observation holes 14 reduce the weight of the protective guard 4, so that the protective guard 4 can be conveniently mounted and dismounted.
The inserting column 2 and the guard rail 4 are jointly provided with a connecting screw hole 15, and the connecting screw hole 15 is spirally matched with a connecting screw rod 16. Due to the arrangement of the connecting screw 16, the protective guard 4 is not easy to fall off from the inserting column 2, and the fixing effect of the inserting column 2 and the protective guard is better.
Referring to fig. 3 and 4, peg graft 2 inside one end center department of being close to fixing base 1 and seted up first chamber 7 that holds, the one end center department of being close to peg graft 2 of fixing base 1 inside has seted up the second and has held chamber 10, first chamber 7 that holds is the column, movable mounting has expanding spring 5 and flexible piece 6 in the first chamber 7 that holds, the one end of expanding spring 5 and the first last bottom surface fixed connection who keeps away from fixing base 1 in holding chamber 7, expanding spring 5's the other end and flexible piece 6 are connected, movable mounting has stopper 8 in the second holds chamber 10, one side swing joint that universal wheel 9 is close to the foundation ditch and faces the limit has two universal wheels 9, the one end fixedly connected with stopper 8 of expanding spring 5 is kept away from to flexible piece 6, stopper 8 is square, the area is greater than the first lower bottom surface area that holds chamber 7. The universal wheel 9 extends or retracts into the second accommodating cavity 10 through the action of the telescopic spring 5.
When the protective guard 4 is not movably inserted into the two insertion columns 2, the insertion columns 2 and the fixing seat 1 are not enough to press the telescopic spring 5 to generate large deformation, the deformation length of the telescopic spring 5 is larger than the extension length of the universal wheel 9, when the protective guard 4 is inserted into the insertion columns 2, the weight of the protective guard and the telescopic spring 5 generate large deformation, and the retraction length of the universal wheel 9 is equal to or larger than the deformation length of the telescopic spring 5. When the guard rail is not movably inserted on the two insertion columns 2, the universal wheel 9 extends out of the second accommodating cavity 10, so that the whole device is easy to move, and when the guard rail 4 is movably inserted on the two insertion columns 2, the universal wheel 9 retracts into the second accommodating cavity 10, so that the fixing seat 1 is easy to fix on the adjacent edge of the foundation pit.
The telescopic block 6 and the inserting column 2 are located on the same axis and provided with a limiting hole 11, a limiting pin 12 is movably mounted in the limiting hole 11, and when the universal wheel 9 is in a contraction state, the limiting pin 12 limits the movement of the telescopic block 6 in the first accommodating cavity 7. So that the universal wheel 9 is more stable in the second accommodating cavity 10 in the contraction state.
The implementation principle that the foundation ditch faces frontier defense guardrail convenient to remove of this application embodiment is:
when the protective guard 4 is not movably inserted into the two inserting columns 2, the weight of the inserting columns 2 and the fixed seat 1 is not enough to press the telescopic spring 5 to generate larger deformation, the deformation length of the telescopic spring 5 is larger than the extension length of the universal wheel 9, when the protective guard 4 is inserted and arranged on the inserting columns 2, the weight of the protective guard 4 and the telescopic spring 5 generate larger deformation, the retraction length of the universal wheel 9 is equal to or larger than the deformation length of the telescopic spring 5, the telescopic block 6 and the inserting columns 2 are positioned on the same axial line and are provided with limit holes 11, limit pins 12 are movably arranged in the limit holes 11, when the universal wheel 9 retracts into the second accommodating cavity 10, the limit pins 12 are inserted into the limit holes 11, so that the telescopic block 6 is fixed, the universal wheel 9 movably connected with the telescopic block 6 is fixed, thereby realizing the support and locking of the protective guard 4, and protecting the edge of a foundation pit by using the protective guard, the influence of the external factors of the foundation pit on the foundation pit is reduced.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the application are all included in the protection scope of the application.
