Abstract

The utility model relates to an angle and distance adjustable dragging clamp seat, which belongs to the technical field of semitrailer and comprises a pedestal (4) and a connecting block body (5), wherein the connecting block body (5) and the pedestal (4) are clamped together; the pedestal (4) is provided with a transmission threaded hole inside which a screw (6) is installed; one end of the screw passes through the connecting block body (5), while the other end is provided with a clamping plate (1); the clamping plate (1) is fixedly connected with the connecting block body (5); wing plates (2) are symmetrically arranged on the left and right sides of the pedestal (4); and the wing plates (2) are rotationally connected with the pedestal. The angle and distance adjustable dragging clamp seat not only can be closely adhered to a saddle type dragging seat to ensure that the steering angle of the tractor is equal to the steering angle of the semitrailer during steering but can also use one dragging clamp seat to be closely adhered with different types of saddle dragging seats manufactured by different manufacturers, thereby achieving interchangeability.

Description

The traction deck of a kind of angle adjustable, distance

Technical field

The utility model relates to the traction deck of a kind of angle adjustable, distance, belongs to the superimposed trailer technical field.

Background technology

At present, common superimposed trailer is through saddle traction seat and towing pin tractor truck partial sum superimposed trailer partly to be coupled together, and only plays the bonded assembly effect, to not effect of semi-trailer direction changing; And the traction deck is housed on the superimposed trailer; The traction deck through the saddle traction seat Angular Dimension of measure to buy returning after processing and manufacturing come out; Guarantee that saddle traction seat and traction deck can fit tightly, the angle that makes superimposed trailer turn over is consistent with the angle that tractor truck turns over, and can not have error; But the angle and distance of the saddle traction seat of different manufacturers different model is all different on the market; Can not fit tightly with the saddle traction seat of different manufacturers different model with a collection of produced traction deck, have certain clearance, promptly interchangeability is very poor.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned deficiency, and the traction deck of a kind of angle adjustable, distance is provided, and it not only can fit tightly with the saddle traction seat, makes the angle of angle that tractor truck turns to and semi-trailer direction changing consistent, does not have error; And same traction deck can fit tightly the realization interchangeability with the saddle of different manufacturers different model.

The purpose of the utility model is achieved in that the traction deck of a kind of angle adjustable, distance, and it comprises base and be connected block that said connection block and base are fastened; Offer the motion thread hole on the said base, said motion thread is equipped with screw rod in the hole, and said screw rod one end passes the connection block; The other end is provided with clamp; Said clamp be connected the block captive joint, said base the right and left is symmetrically arranged with wing plate, said wing plate and base are rotationally connected.

Compared with prior art, the beneficial effect of the utility model is:

The traction deck of a kind of angle adjustable of the utility model, distance; Not only can fit tightly with the saddle traction seat; The angle that tractor truck turned over when assurance turned to is consistent with the angle that superimposed trailer turns over; And the saddle traction seat of same traction deck and different manufacturers different model is fitted tightly, realize interchangeability.

The specific embodiment

Referring to Fig. 1, the utility model relates to the traction deck of a kind of angle adjustable, distance, and it comprises base 4 and is connected block 5; Said connection block 5 is fastened through tolerance fit and base 4; Offer the motion thread hole on the said base 4, said motion thread is equipped with screw rod 6 in the hole, and said screw rod one end passes and connects block 5; The other end is provided with clamp 1; Said clamp 1 be connected block 5 and connect through bolt, said base 4 the right and lefts are symmetrically arranged with wing plate 2, said wing plate 2 is rotationally connected through bearing pin 3 and base 4.

Said wing plate 2 and base 4 are for being rotationally connected; Therefore thereby wing plate 2 can rotate the adjustment angle around base 4; And screw rod 6 is fixedly installed on connection block 5 and the clamp 1; When rotating screw bolt 6, can adjust the position of base 4, thereby adjust the contact position of wing plate 2 and saddle traction seat 8 through the effect in motion thread hole.

Referring to Fig. 2; Be set with saddle traction seat 8 on the tractor truck 7; Towing pin 10 is fixedly mounted on the saddle traction seat 8 through the draw-in groove on the saddle traction seat 8; Angle, distance that traction deck 16 is adjusted himself according to the opening angle and the distance of saddle traction seat 8 fit tightly with it, and traction deck 16 is fixedly set on the base plate of rotating disk joint chair 9, and rotating disk joint chair 9 is captiveed joint with the inner ring of pivoting support 15 through bolt; Captive joint with rotating disk 13 through bolt in the outer ring of pivoting support 15; The rod end of piston cylinder 14 is fixed in through bearing pin between the last twisted point plate 11 and following twisted point plate 12 of rotating disk 13, when tractor truck 7 turns over an angle, drives rotating disk 13 through saddle traction seat 8, traction deck 16, rotating disk joint chair 9 with pivoting support 15 and turns over identical angle; This moment, the rod end of two piston cylinders 14 moved through elongation of rotation of rotating disk 13, a shortening; Big chamber in the piston cylinder links to each other with the fluid-link steering oil cylinder of afterbody through hydraulic tubing, and the motion of afterbody fluid-link steering oil cylinder can realize the rotation of superimposed trailer, and the angle that turns over is consistent with the angle that tractor truck turns over.
