Description
Technical field
The utility model relates to metallurgical equipment installation and maintenance technical field, particularly relates to a kind of special spanner being applicable to flexible transmission device of sintering machine and installing or overhaul.
Background technology
At present, the spanner connecting rod that hexagon socket head cap screw adopts outer six sides is installed or twisted in maintenance process to most flexible transmission device of sintering machine, the length of extension bar is generally regular length, as Chinese patent notification number CN202702196U discloses a kind of integration covering barrel spanner, by two wrenching bars, two link rods and two turning cylinder compositions, the two ends of two wrenching bars are respectively the ut socket of different size, connected by two link rods between two wrenching bars, two link rods lay respectively at the both sides of two wrenching bars, the two ends of two link rods are connected by turning cylinder with two wrenching bars respectively.Such extension bar can only be applicable to single occasion usually, when after transmission device redesigns, its installation site changes, then can make troubles to use, thus needs to change extension bar, causes unnecessary waste.
Utility model content
The utility model is to overcome deficiency of the prior art, provides one and can change extension bar length, use conveniently flexible gearing special spanner.
To achieve these goals, the utility model is by the following technical solutions:
A kind of flexible gearing special spanner, comprise reinforcement handle, sleeve extension rod and expansion link, described expansion link and sleeve extension rod coaxially arranged, the cross section of expansion link is polygon, one end of sleeve extension rod is provided with the elongated hole for holding expansion link, expansion link in elongated hole can relative sleeve extension bar slide axially and on gyratory directions with sleeve extension rod locking, sleeve extension rod is provided with the lock-screw for locating expansion link axial location, described reinforcement handle is provided with transmission tenon, the end face of the other end of sleeve extension rod is provided with the suitable tongue-and-groove of transmission tenon, the outer face of described expansion link is provided with the outer six side's annexes removably connected.Expansion link can move axially by relative sleeve extension bar, and is located by lock-screw, and therefore length can regulate, thus improves adaptability and the versatility of spanner.
As preferably, described sleeve extension rod is provided with the secondary handle that can rotate around sleeve extension rod, and described pair is comprising active ring and can the barre that rotates of relative motion circle, and the pivot center of described barre perpendicular to sleeve extension rod axially.When being positioned at very narrow and small or depression depths wait the bolt tightened, by gripping the secondary gripping convenience improving sleeve extension rod, improve the stability of bolt tightening process middle sleeve extension bar simultaneously.Secondary there is turn over function, so that the angular adjustment of barre and storage.
As preferably, be provided with thrust bearing between described active ring and sleeve extension rod, sleeve extension rod outer surface is provided with spacing ring thrust bearing being carried out to axial location.Thrust bearing is set between such active ring and sleeve extension rod to reduce Relative friction between the two, secondary that the rotation process of relative sleeve extension bar is more smooth and easy, reduce the secondary impact gripping for bolt tightening.
As preferably, the side that described expansion link is positioned at elongated hole one end is provided with positive stop bead and the chute for holding positive stop bead, be provided with limit spring between bottom described positive stop bead and chute, the madial wall of described elongated hole is provided with some stopper slots suitable with positive stop bead.Arrange positive stop bead to coordinate with chute, expansion link can be avoided when regulating length to pull out too fast and be separated with elongated hole, Primary Location can be carried out to expansion link fast simultaneously, being convenient to lock-screw locking.
As preferably, described boom end is embedded with magnet piece in the side near sleeve extension rod.Do not use secondary time, can adsorb to reduce its external dimensions by boom end by magnet piece and sleeve extension rod.
As preferably, described barre outside is provided with rubber sleeve.
The beneficial effects of the utility model are: (1) length can regulate, and to meet different installation requirements, adaptability is high; (2) there is secondary handle, so that grip, improve rundown process stability; (3) pair is passed through angular adjustment, to adapt to be positioned at bolt tightening operation that is narrow and small or depression depths.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: expansion link 1, secondary 2, barre 2a, active ring 2b, thrust bearing 201, spacing ring 202, magnet piece 203, reinforcement handle 3, transmission tenon 3a, limit spring 4, sleeve extension rod 5, stopper slot 5a, chute 5b, tongue-and-groove 5c, lock-screw 6, outer six side's annexes 7, positive stop bead 8.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Embodiment 1: in embodiment as shown in Figure 1, a kind of flexible gearing special spanner, comprise reinforcement handle 3, sleeve extension rod 5 and expansion link 1, expansion link and sleeve extension rod coaxially arranged, the cross section of expansion link is polygon, one end of sleeve extension rod is provided with the elongated hole for holding expansion link, expansion link in elongated hole can relative sleeve extension bar slide axially and on gyratory directions with sleeve extension rod locking, sleeve extension rod is provided with the lock-screw 6 for locating expansion link axial location, reinforcement handle is provided with transmission tenon 3a, the end face of the other end of sleeve extension rod is provided with the suitable tongue-and-groove 5c of transmission tenon, the outer face of expansion link is provided with the outer six side's annexes 7 removably connected.Sleeve extension rod is provided with the pair that can rotate around sleeve extension rod 2, and secondary comprising active ring 2b and can the barre 2a that rotates of relative motion circle, the pivot center of barre is perpendicular to sleeve extension rod axis.Be provided with thrust bearing 201 between active ring and sleeve extension rod, sleeve extension rod outer surface is provided with the spacing ring 202 thrust bearing being carried out to axial location.The side that expansion link is positioned at elongated hole one end is provided with positive stop bead 8 and the chute 5b for holding positive stop bead, and be provided with limit spring 4 between bottom positive stop bead and chute, the madial wall of elongated hole is provided with some stopper slot 5as suitable with positive stop bead.Boom end is embedded with magnet piece 203 in the side near sleeve extension rod, and barre outside is provided with rubber sleeve.
In actual use, when needs use spanner to twist interior hexagonal high-strength bolt, in first one end of outer six side's annexes being inserted in hexagonal High-strength bolt hole, the relative position adjusting expansion link and sleeve extension rod again meets installation requirement length, the transmission falcon of reinforcement handle inserts the tongue-and-groove of sleeve extension rod end, the elongated hole of expansion link outer end aimed at the other end of outer six side's annexes and inserts, thus carrying out tightening or dismantling, so more easily aligning and connect rotation.When installation environment is comparatively narrow or cup depth is larger, can use secondary handle, the barre of revolute handle is adjusted to suitable angle and can be gripped.
