Evenly be provided with a plurality of installation positions on sliding part 21 and the loading portion 22, a plurality of installation positions are the array and arrange, and the quantity of connecting piece 23 is a plurality of, and wherein, connecting piece 23 slidable passes T type groove, and the both ends of a plurality of connecting pieces 23 are detachably installed in a installation position of sliding part 21 and loading portion 22 respectively.
It can be understood, the mounting panel of two rectangular shapes that sliding part 21 and loading portion 22 were parallel to each other and the interval set up, the mounting hole has all been seted up to the mounting panel, the mounting hole is the array and arranges, and the mounting hole one-to-one setting of two mounting panels, the mounting hole constitutes the installation position of erection joint spare 23, connecting piece 23 is cylindrically, and the mounting hole of two relative mounting panels in both ends of connecting piece 23 all sets up threaded hole, the mounting hole of two mounting panels is passed respectively to the screwed end through two screws (not shown in the figure), and make screw threaded connection in the screw hole at the both ends of connecting piece 23 respectively, connecting piece 23 and two mounting panels's dismantling and being connected have been realized.
If the two mounting plates are fixed together in a welding mode, the flatness of the two mounting plates can be influenced, the two mounting plates are connected through the connecting piece 23 and the screw, and the two mounting plates are prevented from being directly connected in a welding mode; in order to avoid the loosening of the screws, the screws are welded with the two mounting plates after being screwed down, so that the loosening of the screws is avoided.
The weight member 24 is at least one, is disposed at a predetermined position between the sliding portion 21 and the loading portion 22, and is connected to both the sliding portion 21 and the loading portion 22. Because the quantity of installation position is a plurality of and be the array and arrange for the quantity and the mounted position of connecting piece 23 can arrange as required, and different arrangement forms different installation balancing weight 24's the position of predetermineeing, for example the one end of mounting panel, middle part and the other end, can also set up according to the weight distribution characteristics of actual loading thing, so that the whole weight and the weight distribution of counter weight component 2 accord with actual loading thing, can better simulate actual loading condition.
It is understood that the weight 24 can be a block of various shapes, in this embodiment, the weight 24 is a rectangular block, and the weight 24 can be designed into various shapes, so that the weight 24 forms different weight distributions in the weight assembly 2.
In the present embodiment, the weight 24 is located at one end of the mounting plate; through setting up balancing weight 24 in the one end on the mounting panel, when counterweight assembly 2 is located treating the loading object 3 on, the skew counterweight assembly 2's of balancing weight 24 center for counterweight assembly 2's weight is partial to one end, and the condition that human head and feet are light can be simulated in this kind of setting, and the human weight distribution of simulation that can be better simulates the human body and carries out the load test.
It can be understood that the counterweight block 24 can also be connected to the bottom of the loading portion 22, and the counterweight block 24 can include a plurality of weights vertically arranged in sequence, and the weights are connected with each other through a rope, so that when the object 3 to be loaded is lifted, the object 3 to be loaded gradually supports each weight, and the gradual loading of the object 3 to be loaded is realized.
Through setting up the cover body 25, the cover body 25 surrounds connecting piece 23 and balancing weight 24 that set up between sliding part 21 and loading portion 22, can avoid objects such as finger or arm to contact balancing weight 24 and connecting piece 23, avoids sliding counterweight assembly 2's in-process, and connecting piece 23 and balancing weight 24 are drawn into objects such as finger or arm, eliminate the potential safety hazard.
In the present embodiment, the limiting member 26 is used for limiting the counterweight assembly 2 to slide relative to the fixing member 11. Because the sliding portion 21 is detachably and slidably disposed in the mounting groove 11a, by disposing the limiting member 26 on the fixing component 11, the limiting member 26 realizes the limiting of the sliding portion 21 with respect to the fixing component 11, so as to prevent the sliding portion 21 from sliding with respect to the fixing component 11, and prevent the counterweight assembly 2 from falling off from the fixing component 11.
As shown in fig. 4, the stopper 26 is a bolt, and a screw end of the bolt is screwed to the fixed member 11 and is disposed on the movement locus of the sliding portion 21. In the process of pushing the fixing part 11 and the counterweight assembly 2 to move, the fixing part 11 stops moving suddenly and may cause the counterweight assembly 2 to slide out from the rear of the fixing part 11, and the counterweight assembly 2 can be prevented from sliding out from the rear of the fixing part 11 by arranging two bolts connected with the fixing part 11.
In an embodiment of the present invention, the weight assembly 2 further comprises three handles 27, wherein two handles 27 are disposed at one end of the fixing member 11 and the other handle is disposed at the other end of the fixing member 11, and are connected to the fixing member 11.
