Description
Technical Field
The utility model relates to a low flat-bed semi-trailer field, specific theory has related to a low flat-bed semi-trailer gooseneck spare tyre fixing device and semitrailer.
Background
The front end width of the gooseneck longitudinal beam of the existing low-flat-plate gooseneck semitrailer is narrower than that of a frame, and when the requirement of loading engineering machinery is met, the space and the position for reserving and installing spare tires are limited; in addition, the space for installing the spare tire is not suitable to be reserved on the bearing surface of the rear frame and below the bearing surfaces on the two sides of the frame. Then the front end of the low-flat gooseneck longitudinal beam is not generally used as a bearing part, so that the space at the front end of the low-flat gooseneck longitudinal beam can meet the requirement for placing a spare tire of a vehicle; but the current low-plate gooseneck longitudinal beam does not have a special tool for fixing the spare tire. In order to solve the problem of the stability of the spare tire, the patent application CN202022524727 discloses a spare tire fixing device and a tractor with the same, wherein the device is fixed in a bolt hole on a hub by using a long bolt, but the fixing mode has the risk of the rotation of the spare tire.
In order to solve the above problems, people are always seeking an ideal technical solution.
SUMMERY OF THE UTILITY MODEL
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: a gooseneck spare tire fixing device for a low-flat-bed semitrailer comprises a semitrailer gooseneck, wherein a spare tire fixing support is arranged on the semitrailer gooseneck, a fixing bolt rod is vertically arranged on the spare tire fixing support, a spare tire pressing plate is movably arranged on the fixing bolt rod, and a pair of anti-rotation pins are arranged on the spare tire pressing plate; and the top of the fixed bolt rod is provided with a nut.
Based on the above, in order to make full use of the space, the spare tire rack fixing support is arranged in the middle of the gooseneck of the semitrailer.
Based on the above, the middle part of the spare tire pressure plate penetrates through the fixed bolt rod.
Based on the above, the length of the spare tire pressing plate is smaller than the width of the gooseneck of the semitrailer.
Based on the above, in order to fix firmly, the spare tire carrier fixing support is arranged perpendicular to the fixing bolt rod.
The utility model also provides an install this low flatbed semitrailer gooseneck spare tyre fixing device's semitrailer.
The utility model discloses relative prior art has substantive characteristics and progress, specific theory, the utility model provides a low dull and stereotyped semitrailer gooseneck spare tyre fixing device at low dull and stereotyped gooseneck longeron front end design spare tyre fixing device, makes things convenient for the vehicle spare tyre to install, dismantle from trailer the place ahead. Meanwhile, the front end of the gooseneck longitudinal beam is not generally used as a bearing part, so that the loading space and the equipment space of the vehicle can be maximally utilized.
Furthermore, the spare tire fixing device can meet the requirement of installing and fixing the used spare tires of the common semitrailer in different sizes by changing the length of the spare tire pressing plate.
Furthermore, the device adopts the design of the fixed bolt rod, the spare tire pressing plate and the anti-rotation pin, can prevent the spare tire from shaking and sounding after being installed, and avoids the tire damage caused by the collision of the side surface of the tire and the vehicle body.

Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
This reality is a low flatbed semitrailer gooseneck spare tyre fixing device, as shown in fig. 1, fig. 2 and fig. 3, including semitrailer gooseneck 1, be provided with the fixed 5 that props of spare tyre on the semitrailer gooseneck 1, the fixed 5 last vertical fixed bolt pole 4 that is provided with of propping of spare tyre.
A spare tire pressing plate 2 is movably arranged on the fixed bolt rod 4, and a pair of anti-rotation pins 3 are arranged on the spare tire pressing plate 2; the top of the fixed bolt rod 4 is provided with a nut.
In order to fully utilize the space, the spare tire rack fixing support 5 is arranged in the middle of the semitrailer gooseneck 1. The middle part of the spare tire pressure plate 2 penetrates through the fixed bolt rod 4.
The length of the spare tire pressing plate 2 is smaller than the width of the semitrailer gooseneck 1.
For firm fixation, the spare tire frame fixing support 5 is arranged perpendicular to the fixing bolt rod 4.
The embodiment also provides the semitrailer provided with the gooseneck spare tire fixing device of the low flatbed semitrailer.
Specifically, as shown in fig. 3, when the low flatbed semitrailer gooseneck spare tire fixing device is used for fixing the spare tire 6, the specific operation steps are as follows:
firstly, loosening a nut at the top end of a fixed bolt rod, and taking down a spare tire pressure plate and an anti-rotation pin from the fixed bolt rod; then the center of the spare tire is placed on a fixed support of a spare tire frame through a fixed bolt rod; then, mounting the spare tire pressing plate and the anti-rotation pin on the fixed bolt rod, and fixing the anti-rotation pin in a bolt hole on the spare tire; and finally, the nut at the top of the fixed bolt rod is screwed down to press the spare tire between the spare tire pressing plate and the spare tire frame fixing support.
