Embodiment
Be described in further detail utility model object of the present utility model below in conjunction with the drawings and specific embodiments, embodiment can not repeat one by one at this, but therefore embodiment of the present utility model is not defined in following examples.
embodiment one
As shown in Figures 1 to 7, a kind of road surface transmission rod shearing clamp, comprise clamping fixture table 1 and shear platform 2, described clamping fixture table 1 comprises jig main body, be arranged at the combinatorial cylinders mounting hole 11 in jig main body, slide in described combinatorial cylinders mounting hole 11 and be provided with the combinatorial cylinders 5 consistent with combinatorial cylinders mounting hole 11 shape, described combinatorial cylinders 5 forms by cylindrical-shaped main body with along the rectangular preiection 51 that cylindrical-shaped main body length direction projection is arranged on cylindrical-shaped main body outer wall, the endoporus of described cylindrical-shaped main body is consistent with transmission rod diameter, the symmetria bilateralis of described clamping fixture table 1 is provided with rail arms 12, relatively rectangular guideway groove 13 is vertically provided with inside described rail arms 12, be provided with the sleeve mounting hole 22 for installing circular sleeve 3 in described shear platform 2, described circular sleeve 3 diameter of bore is consistent with transmission rod diameter, is vertically provided with to symmetria bilateralis the rectangular rail 21 matched with rectangular guideway groove 13.
L shape tracks positioned grid 4 are also provided with in described rectangular guideway groove 13.
Be provided with hemispheric location counterbore 23 to the intermediate recess of described shear platform 2 upper surface.
In the present embodiment, each component materials selects high rigidity iron or high-carbon steel, transmission rod diameter 40mm to be sheared, namely described circular sleeve 3 and combinatorial cylinders 5 circle diameter of bore are 40mm, simultaneously, be 5mm to make the joint gap of shearing place of clamping fixture table 1 and shear platform 2, therefore the width of tracks positioned grid 4 is 15mm, during installation, tracks positioned grid 4 to be inserted in rectangular guideway groove 13 and to be positioned at the seam side of rectangular rail 21 away from shearing place, in the present embodiment, the rectangular rail 21 of shear platform 2 both sides and the joint spacing 40mm of shearing place.
