Abstract
The utility model belongs to the technical field of manhole cover, and discloses a theft-proof manhole cover which is characterized in that the utility model comprises a cover body, wherein the bottom surface of the cover body is fixed with a rotary arm and a hydraulic mechanism. Both ends of the rotary arm are respectively connected with a first pull rod and a second pull rod, and the top ends of the first pull rod and the second pull rod are respectively connected with a first locking block and a second locking block. One end of the rotary arm, which is connected with the first pull rod, is connected with an output shaft of the hydraulic mechanism. The top surface of the cover body is provided with a groove provided with a locking cover, and a hydraulic conveying end head of the hydraulic mechanism is fixed in the groove. The theft-proof manhole cover provided by the utility model only can finish work by using a hydraulic pump in the processes of installation and dismounting, and has the advantages of favorable theft-proof effect and simple operation.
Description
Technical field
The utility model belongs to the well lid technical field, relates in particular to a kind of anti-stealing manhole cover.
Background technology
In urban construction, manhole, gate shaft, measuring well that is used for water supply and drainage, combustion gas and heat distribution pipeline, electricity cable, telecom communication etc. etc. all needs well lid.The well lid of current use adopts material such as cast iron to make mostly, and the stolen phenomenon of well lid takes place repeatedly, not only influences traffic, and cause very big danger can for vehicle and pedestrian, especially at night, dangerous can be bigger.
The utility model content
The purpose of this utility model just provides a kind of anti-stealing manhole cover that adopts specialist tools just can take off that has only.
The technical solution adopted in the utility model is: comprise lid, the bottom surface of described lid is fixed with pivoted arm and hydraulic mechanism, the two ends of described pivoted arm are connected with first pull bar and second pull bar respectively, the top of first pull bar and second pull bar is connected with first lock dog and second lock dog respectively, an end that is connected with first pull bar of described pivoted arm is connected with the output shaft of hydraulic mechanism, the end face of described lid has a lid groove with lock, and the liquid of described hydraulic mechanism carries the termination to be fixed in the groove.
Its additional technical feature is: described first pull bar is connected with pivoted arm with second sleeve by first sleeve respectively with second pull bar, first pull bar and the first sleeve junction are provided with first spring, and second pull bar and the second sleeve junction are provided with second spring; Described pivoted arm is provided with the 3rd spring and the 4th spring that an end is fixed on the lid bottom surface near first pull bar and the second pull bar place; Described first lock dog and second lock dog pass the retainer ring that is fixed in the lid bottom surface respectively.
Anti-stealing manhole cover provided by the utility model compared with prior art, by bottom surface pivoted arm and hydraulic mechanism are set at lid, and the pull bar of connecting band lock dog on the pivoted arm after installing well lid, carries the termination to be connected with hydraulic pump the liquid of hydraulic mechanism, the primer fluid press pump makes the output shaft retraction of hydraulic mechanism and pulling pivoted arm clockwise rotate, the pull bar movement therewith, in the hole on the lock dog fill-in well decorative cover, well lid is locked, remove hydraulic pump, groove is built and locked get final product.When needing the dismounting well lid, open the locking closure of groove, carry the termination to be connected the liquid of hydraulic mechanism with hydraulic pump, the primer fluid press pump makes the output shaft of hydraulic mechanism stretch out and promotes pivoted arm and rotates counterclockwise, the pull bar movement therewith, be drawn out in the hole on the lock dog well cover cycle, well lid can be removed.In this process, well lid has only the hydraulic pump of use just can finish dismounting, can play good anti-theft effect.
Description of drawings
Accompanying drawing is the structural representation of the utility model anti-stealing manhole cover.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model anti-stealing manhole cover.
As shown in Figure 1, the utility model anti-stealing manhole cover comprises lid 1, be fixed with pivoted arm 2 and hydraulic mechanism 3 in the bottom surface of lid 1, pivoted arm 2 is connected with the output shaft 4 of hydraulic mechanism 3, pivoted arm 2 is connected with first pull bar 5 and second pull bar 6, first pull bar, 5 one ends have first lock dog 7, the other end has first sleeve 8, one end of second pull bar 6 has second lock dog 9, the other end has second sleeve 10, first pull bar 5 and first sleeve, 8 junctions have first spring, 11, the second pull bars 6 and second sleeve, 10 junctions that second spring 12 is arranged, and pivoted arm 2 has the 3rd spring 13 and the 4th spring 14 near first pull bar 5 and second pull bar, 6 places, the end face of lid 1 has the groove 15 of a lid with lock, the liquid of hydraulic mechanism 3 is carried termination 16,17 are fixed in the groove 15, and first lock dog 7 passes first retainer ring, 18, the second lock dogs 9 and passes second retainer ring 19.Be provided with conveying termination 21,22 with the matching used hydraulic pump 20 of anti-stealing manhole cover.
During use, carry termination 16,17 to be connected with the liquid of hydraulic mechanism 3 the conveying termination 21,22 of hydraulic pump 20, primer fluid press pump 20, make the output shaft 4 of hydraulic mechanism 3 bounce back, the retraction pulling pivoted arm 2 of output shaft 4 clockwise rotates first pull bar 5 and second pull bar, 6 movement therewith, in the hole 24 on first lock dog 7 and second lock dog, the 9 fill-in well decorative covers 23, lid 1 is locked, and removes hydraulic pump 20 then, groove 15 is built and locked get final product.
When needing the dismounting well lid, open the locking closure of groove 15 earlier, carry termination 16,17 to be connected with the liquid of hydraulic mechanism 3 the conveying termination 21,22 of hydraulic pump 20, primer fluid press pump 20, make the output shaft 4 of hydraulic mechanism 3 stretch out, the promotion pivoted arm 2 that stretches out of output shaft 4 rotates counterclockwise first pull bar 5 and second pull bar, 6 movement therewith, be drawn out in first lock dog 7 and second lock dog 9 hole 24 from the well cover cycle 23, well lid can be removed.
There is first spring 11 first pull bar 5 and first sleeve, 8 junctions, there is second spring 12 second pull bar 6 and second sleeve, 10 junctions, pivoted arm 2 has the 3rd spring 13 and the 4th spring 14 near first pull bar 5 and second pull bar, 6 places, after well lid is locked, because the elasticity of spring, make pivoted arm 2 first lock dog 7 and second lock dog 9 tightly are pressed in the hole 24 on the well cover cycle 23, prevent first lock dog 7 and second lock dog, the 9 loosening holes 24 that break away from the well cover cycles 23 by first pull bar 5 and second pull bar 6.
