Abstract

The utility model provides a conveying rack. The front ends and the rear ends of two parallel guide rails are connected by baffles respectively to form a rectangular frame; a reinforcing beam is connected between the two baffles; hooks are fixedly connected with the underneathes of the front ends of the guide rails; the underneath of the reinforcing beam is articulated with one end of a sleeve; the other end of the sleeve is connected with one end of a supporting fork in a sleeving manner; the other end of the supporting fork is articulated with testing equipment; a supporting rod moves telescopically in the sleeve; and when the supporting rod extends to a right position, a spring clamp pin penetrates through an external wall of the sleeve and extends into a pin hole in a wall of the supporting rod to lock the supporting rod and the sleeve. The conveying rack is light in weight, easy to operate, and high in stability, and can be operated by just one person.

Description

Conveying rack

Technical field

The invention belongs to the loading and unloading series products, be applicable to the test of rainfall bullet before dispatching from the factory, for the loading and unloading that the rainfall bullet are transported on test equipment.

Background technology

Conveying rack is that the rainfall bullet is transported to device on test equipment, and existing conveying rack needs the operator more than three to cooperatively interact when operation, and this causes because of fulcrum is unstable.Except the personnel of operation conveying rack, also to there be the special messenger to be responsible for stablizing fulcrum, the time that has caused transporting operation is longer, has reduced testing efficiency.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of conveying rack, test equipment provides fast, the failure-free device for the rainfall bullet is transported to.

the technical solution adopted for the present invention to solve the technical problems is: comprise guide rail, baffle plate, strength beam, hook, sleeve and stay fork, two parallel guide rails connect by baffle plate respectively in the rear and front end, the framework that forms rectangle, connecting-reinforcing beams between two baffle plates, hook is connected below the guide rail front end, the strength beam below is hinged with sleeve one end, sleeve other end socket stay fork one end, the other end of stay fork is hinged on the equipment of survey, strut bar is fore and aft motion in sleeve, after elongation puts in place, spring detent passes sleeve outer wall and stretches into pin-and-hole on the strut bar wall, locked strut bar and sleeve.

Be provided with handle on the baffle plate of guide rail rear end.

The invention has the beneficial effects as follows:

At first advantage of the present invention is that Operating Weight is light, will transport guide rail and framework unites two into one, and merges wherein, has both solved and the docking of test equipment, and has deleted again the structure of redundancy on weight, and weight saving makes operation easier.Next is that stability strengthens, utilize the principle of triangle stability, to form triangular support structure after conveying rack motion puts in place and between test equipment, even if rocking yet that test equipment is slight can not exert an influence to the support of conveying rack, this also makes operation become easy, the operator only need to upwards lift until strut bar is automatically locked at the end of the conveying rack handle of holding with a firm grip, and this operation only needs a people to carry out.

The specific embodiment

The present invention is further described below in conjunction with drawings and Examples.

For realizing that the rainfall bullet is delivered in test equipment, the invention provides quick, failure-free device.

The composition of conveying rack is as shown in Fig. 1 (a) and (b) (c), and the framework of being responsible for main carrying is comprised of guide rail 1 and baffle plate 2,

strength beam

3, and 1 two left-right symmetric of its middle guide had both played the supporting role of framework, were also the guide tracks that transports the rainfall bullet; Baffle plate 2 one in front and one in back is welded on conveying rack, plays the front and back position-limiting action of restriction rainfall bullet in handling process; Strength beam 3 and guide rail 1, baffle plate 2 are welded to form the main frame of conveying rack, can carry enough weight.

Hook 4 left-right symmetric of conveying rack front end are welded on respectively the below of left and right rail 1, and totally two is the point of connection of conveying rack and rainfall bullet test equipment, the fulcrum when being also the conveying rack motion.

the difference of different leveling height when at every turn using in order to break away from test equipment, so another hinge-point of conveying rack is arranged on the framework of test equipment self, it is the hinge-point place that stay fork 5 can be arranged on test equipment easily, therefore the moving displacement of conveying rack is set with the vertical distance of stay fork 5 by hook 4, and it is irrelevant apart from the height on ground with test equipment, realize that this displacement is mainly the cooperation that relies on strut bar 6 and sleeve 7, they are positioned at the bottom of conveying rack, the operation conveying rack, strut bar 6 seesaws in the inside of sleeve 7, after moving displacement puts in place, a spring detent 8 of sleeve 7 outsides will spring into automatically, locked strut bar 6 and sleeve 7.Certainly, for the ease of personnel's operation, at the rear afterbody of conveying rack, handle 9 is set, is welded on support body each of left-right symmetric, profile meets the requirement of human engineering.

After strut bar 6 and sleeve 7 arrived the displacement of setting and be automatically locked, conveying rack just was connected with test equipment and puts in place, manually promotes the rainfall bullet and enters in test equipment, and the process of transporting is completed.

The entire length size A=1000mm of conveying rack, height dimension B=200mm, main body frame adopt the 20# steel to be welded, the center size C=450mm of anterior two hooks of conveying rack, guide rail 1 adopts steel angle structure, the space D=300mm of two guide rails.

The initial condition of conveying rack motion is that the O point lands, this moment, strut bar 6 should be retracted in sleeve 7 fully, according to the some P point that conveying rack is connected with test equipment, the height distance that Q is ordered calculates the travel displacement of strut bar 6, and sets the position dimension of R point before and after conveying rack.

During use such as Fig. 2 (a), shown in Fig. 2 (b), the position of hook 4 and stay fork 5 has been fixed on test equipment, no matter how conveying rack moves, and their relative position can not change, and holds handle 9 and upwards lifts, this moment, strut bar 6 stretched out from sleeve 7, until spring detent 8 is automatically locked, guide rail 1 was horizontal and docked with test equipment this moment, and the task of conveying rack is completed.

Above conveying rack promotes the rainfall bullet and enters test equipment with after test equipment docks, and the process of transporting is completed, as shown in Figure 3.

The scantling of structure A of conveying rack in the present invention, B are according to the dimensioned of rainfall bullet, and scantling of structure C, D are according to the dimensioned of test equipment.
