Detailed Description
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The invention will be described in detail below with reference to the drawings in connection with embodiments.
As described in the background art, at present, when the tray falls into the ground supporting device, there is a problem of alignment difficulty, the tray needs to be continuously adjusted to fall into the ground supporting device, so that loading and unloading efficiency is greatly reduced, after the ground supporting device is matched with the tray, the tire bearing surface is in a horizontal state, and as the lower plane of the semi-trailer supporting device is higher than the ground by a certain distance, the semi-trailer can be in a front low and rear high 'low head' state after being loaded into the tray. When the inclination of the semitrailer is large, the tractor cannot be connected with the semitrailer, and the unloading efficiency of the semitrailer is affected.
In order to solve the above-described problems, referring to fig. 1 to 7, an embodiment of the present invention provides a tray auxiliary device including a main body 10, the main body 10 being installed on the ground; the main body 10 is provided with a receiving groove 11, and the receiving groove 11 is used for receiving the bottom structure of the tray 30; at least one groove wall of the accommodating groove 11 is provided with a guide surface 12, which is inclined, specifically gradually inclined toward the inner side of the accommodating groove 11 from top to bottom.
Because the tray is suspended by the crane when the semi-trailer is conveyed by the tray, and then the tray is placed into the tray auxiliary device for fixing, the position of the tray is difficult to control in the suspension conveying process of the crane, so that the tray loading process is difficult and the efficiency is low.
Since the fixed position of the tray needs to be replaced during piggyback transportation, the main body 10 in this embodiment is detachably installed on the ground for cost saving, and the tray auxiliary device further includes a plurality of hanging parts 20 provided on both sides of the main body 10, specifically, on both sides in the width direction of the main body. When the fixed position of the tray needs to be adjusted, a worker can detach the main body from the ground and connect the lifting rope on the suspension part, the main body is suspended by the crane and moves to the designated position, the position adjustment is completed, the tray fixing at a plurality of positions can be met only by a small number of tray auxiliary devices, and the cost is saved. The main body can be connected with the ground by bolts or other modes.
Preferably, the body of the present application is made of steel, the body being integrally formed with the suspension.
Preferably, guide surfaces are provided on both front and rear groove walls of the receiving groove.
Preferably, the plurality of hanging parts 20 in the present embodiment are arranged in pairs, and two hanging parts 20 of each pair are symmetrically arranged at both sides of the main body 10 in the length direction, so that the hanging of the main body is more balanced, and the main body is prevented from rotating and turning on one's side.
Specifically, the suspension portion 20 in the present embodiment includes a suspension seat, and a suspension recess 21 is provided on the outer side of the suspension seat. When the fixed position of the tray needs to be adjusted, a worker can connect the lifting hook of the lifting rope on the hanging concave part, hang the main body through the crane and move to the designated position to finish position adjustment.
As shown in fig. 4, the present invention improves the inner side wall of the suspension part to avoid the influence of the suspension part on the loading of the tray while facilitating the movement by providing the suspension part, specifically, the inner side wall of the suspension part 20 in the present embodiment is provided with the first guiding inclined surface 22, and the first guiding inclined surface 22 is inclined, specifically, gradually inclined toward the inner side of the main body 10 from top to bottom. The bottom structure of the tray is guided through the first guide inclined plane, so that workers can quickly align with the accommodating groove and install and fix the accommodating groove in the process of moving the tray, and the fixing efficiency of the tray is effectively improved.
Because the semitrailer can present the high "low head" state in front of and behind after loading into the tray, when semitrailer inclination is great, lead to the tractor unable to link with the semitrailer, influence semitrailer unloading efficiency. The main body 10 in this embodiment is provided with a bearing portion 13, the accommodating groove 11 is provided on the bearing portion 13, the bearing portion 13 extends along the length direction of the main body 10, and the upper end surface of the bearing portion 13 gradually slopes upward from the rear end of the tray to the front end of the tray 30. The front-back direction of the tray is the same as the front-back direction of the semitrailer, and the upper end face of the bearing part is gradually inclined upwards from the rear end of the tray to the front end of the tray 30, so that the front low-back high state of the semitrailer can be counteracted, and preferably, the inclination angle of the upper end face of the bearing part is opposite to the inclination angle of the semitrailer, so that the semitrailer is kept horizontal.
In order to facilitate disassembly and assembly of the semitrailer, the two ends of the main body 10 in the length direction in the present embodiment are provided with the cab apron 40, the bearing portion 13 is provided between the two cab apron 40, and each cab apron 40 gradually decreases toward the outside of the main body 10 in the length direction of the main body 10. Through setting up the cab apron for the wheel of semitrailer can be smooth and easy upper and lower tray and tray auxiliary device.
In order to mate with the bottom of the tray, the rear end of the bearing portion 13 in this embodiment is provided with a plurality of grooves 14, and the positions of the projections formed between the adjacent two grooves 14 correspond to the positions of the tire holes at the bottom of the tray 30.
To further facilitate the mounting of the tray, at least one of the groove walls of the groove 14 in the present embodiment is provided with a second guiding slope, which gradually slopes inward of the groove 14 from top to bottom. The tray is guided through the second guide inclined plane, so that the tray can be installed more smoothly.
Preferably, the accommodating groove 11 in the present embodiment is provided at the front end of the bearing portion 13, and the inclination angle of the bottom wall of the accommodating groove 11 and the inclination angle of the bottom wall of the recess 14 are the same as the inclination angle of the upper end face of the bearing portion 13.
From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
because the tray is suspended by the crane when the semi-trailer is conveyed by the tray, and then the tray is placed into the tray auxiliary device for fixing, the position of the tray is difficult to control in the suspension conveying process of the crane, so that the tray loading process is difficult and the efficiency is low.
