Description
Technical field
The utility model relates to a kind of telescopic access board apparatus that connects bank for jumping wholesale.
Background technology
Jumping wholesale on barge is at present connected with riverbank, the mode that main dependence a dead lift is wooden or aluminium matter springboard is set up, need need constantly adjust the length that springboard is set up along with rising of river moves back, this situation is labor intensive not only, labour intensity is large, and springboard can not be effectively fixing, easily rocks, slides, be hooked insecurely, produce and easily to make the overboard potential safety hazard of people.
Utility model content
The purpose of this utility model is for prior art above shortcomings, and a kind of telescopic access board apparatus is provided, and it has advantages of conserve space, time saving and energy saving, convenient and practical, and is hooked firmly, and safety factor is greatly enhanced.
For achieving the above object, telescopic access board apparatus of the present utility model, comprise and jump wholesale, it is characterized in that jumping wholesale upper groove, in groove is solid, be provided with springboard box, in springboard box, both sides are all provided with gear by mandrel, and mandrel and gear pass through key connecting, the jumping wholesale deck of a mandrel top is provided with perforate therein, and one handle is connected through perforate and this mandrel; In springboard box, be provided with telescopic gangway, the tooth bar that the both sides of telescopic gangway all set firmly with gear meshes separately, both sides, rear end at telescopic gangway are equipped with at least one roller, at the front end of jumping wholesale, are installed with support, are provided with the front support axle being positioned at below telescopic gangway on support.
The utility model rotates by handle band moving mandrel, gear, then by the transmission of wheel and rack, telescopic gangway can be moved forward and backward, and telescopic gangway can stretch in springboard box, to adjust the length of setting up, operates time saving and energy saving, convenient and practical; Simultaneously springboard moves and fix in the springboard box of rigid construction, is also the linear movement guide of springboard, and physical construction is tight, rocks gap little, is hooked firm; Front support axle can improve the bearing capacity of telescopic gangway;
As further improvement of the utility model, springboard box comprises two channel-section steels that welding is connected, and the both sides, rear end of telescopic gangway are equipped with two rollers, and two rollers touch with the upper and lower edge joint of corresponding channel-section steel respectively; Not only springboard box is made simply, and the upper and lower sides of telescopic gangway all contacts with springboard box by roller, plays the support of springboard afterbody weight, is hooked more firmly, and reduces resistance of motion;
As further improvement of the utility model, groove is provided with the removable cover concordant with jumping wholesale deck; Be convenient to device maintenance;
As further improvement of the utility model, front support axle is located on support by the plain bearing at two ends; Front support axle is rotated by bearing, has reduced the friction of motion resistance of springboard and front support axle;
In sum, the utlity model has conserve space, time saving and energy saving, convenient and practical advantage, and be hooked firmly, safety factor is greatly enhanced.
Accompanying drawing explanation
Fig. 1 is the birds-eye view of the utility model embodiment.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 2, this telescopic access board apparatus, comprises and jumps wholesale 1, in jumping wholesale 1, is provided with groove 2, and groove 2 is provided with and jumps the concordant removable cover 3 in wholesale deck; In groove 2 is solid, be provided with springboard box 4, springboard box 4 comprises two channel-section steels that welding is connected, in the interior both sides of springboard box 4, all by mandrel 5, be provided with gear 6, mandrel 5 passes through key connecting with gear 6, the wholesale of the jumping of mandrel 5 tops therein deck is provided with perforate 7, and one handle 8 is connected through perforate 7 and this mandrel 5; In springboard box 4, be provided with telescopic gangway 9, the tooth bar 10 that the both sides of telescopic gangway 9 all set firmly with gear 6 meshes separately, is equipped with 11, two rollers 11 of two rollers and touches with the upper and lower edge joint of corresponding channel-section steel respectively in the both sides, rear end of telescopic gangway 9; At the front end of jumping wholesale 1, be installed with support 12, front support axle 13 is located on support 12 by the plain bearing 15 at two ends, and front support axle 13 is positioned at telescopic gangway 9 belows;
The utility model rotates by handle 8 band moving mandrels 5, gear 6, by gear 6 and the transmission of tooth bar 10, telescopic gangway 9 can be moved forward and backward again, telescopic gangway 9 can stretch in springboard box 4, reaches required length and can be abutted against bank, operates time saving and energy saving, convenient and practical; Simultaneous retractable springboard 9 moves and fixes in the springboard box 4 of rigid construction, it is also the linear movement guide of telescopic gangway 9, the upper and lower sides of telescopic gangway 9 all contacts with springboard box 4 by roller 11, play the support of springboard afterbody weight, be hooked more firmly, and reduce resistance of motion, this physical construction is tight, rock gap little, safety factor is greatly enhanced; Front support axle 13 can improve the bearing capacity of telescopic gangway 9, and is rotated by plain bearing 15, has reduced the friction of motion resistance of telescopic gangway 9 with front support axle 13.
