[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] An installation mechanism for a tram guardrail includes a first bottom strip 1, a second bottom strip 2 and two groups of guardrail members 3. Screw sleeves 7 are fixedly installed at the bottoms of the vertical ends of the two groups of guardrail members 3. The two groups of screw sleeves 7 are respectively slidably connected to the inner surface of the first bottom strip 1 through two horizontally arranged horizontal grooves 10. A stability-maintaining component for maintaining the stable movement of the two groups of guardrail members 3 is arranged on the inner surface of the second bottom strip 2, and a driving component for driving the two groups of screw sleeves 7 to move relative to each other is arranged on the inner surface of the first bottom strip 1;

[0025] The first bottom strip 1 and the second bottom strip 2 are respectively fixedly installed on both sides of the longitudinal end of an external lifting seat. In the initial state, the screw sleeve 7 engages with the screw rod 8, and the guardrail member 3 remains stable. Subsequently, the two output ends of the bidirectional motor 4 drive the two screw rods 8 to rotate. The two screw rods 8 are respectively screwed with the two screw sleeves 7. While the two screw sleeves 7 slide along the two horizontal grooves 10 respectively, they respectively provide traction forces for the two groups of guardrail members 3. The slide blocks 5 at the bottoms of the two groups of guardrail members 3 slide synchronously along the slide grooves 6 on the inner surface of the second bottom strip 2, so that the two groups of guardrail members 3 move relative to each other until the distance between the two groups of guardrail members 3 reaches the specified requirement. While realizing the installation of the guardrail in this way, the guardrail can be conveniently adjusted in position according to the size of the goods.

[0026] Specifically, as Figure 2 And Figure 4As shown in the figure, inner grooves 11 are provided on the inner surfaces of the first bottom strip 1 and the second bottom strip 2. Locking rods 12 penetrate through the inner surfaces of multiple groups of inner grooves 11, and rubber blocks 9 are in interference fit with the inner surfaces of multiple groups of inner grooves 11. Multiple groups of rubber blocks 9 respectively abut against the outer surfaces of multiple groups of locking rods 12. After placing the first bottom strip 1 and the second bottom strip 2 on both sides of the longitudinal end of the external lifting seat, and inserting multiple groups of locking rods 12 into the inner grooves 11 on the first bottom strip 1 and the second bottom strip 2 respectively, the fixation of the first bottom strip 1 and the second bottom strip 2 to the lifting seat is completed. Then, multiple groups of rubber blocks 9 can be respectively combined into multiple groups of inner grooves 11. The interference fit method ensures the stable position of the rubber blocks 9. The rubber blocks 9 will abut against the outside of the locking rods 12, thereby restricting the loosening of the locking rods 12 through friction.

[0027] Specifically, as Figure 2 shown in Figure 3 the figure, the driving assembly includes a bidirectional motor 4. The bidirectional motor 4 is fixedly installed on the inner surface of the first bottom strip 1. Screw rods 8 are fixedly connected to the outer surfaces of the two output ends of the bidirectional motor 4. The two screw rods 8 are respectively in threaded connection with two screw sleeves 7. The two output ends of the bidirectional motor 4 drive the two screw rods 8 to rotate. The two screw rods 8 are respectively in threaded connection with the two screw sleeves 7. While the two screw sleeves 7 slide along the two transverse grooves 10 respectively, they respectively provide traction for the two guardrail members 3. The stability maintenance assembly includes two sliders 5. The second bottom strip 2 is slidably connected to the two sliders 5 through a chute 6. The two sliders 5 are respectively fixedly connected to the bottoms of the two guardrail members 3. The sliders 5 at the bottoms of the two guardrail members 3 slide synchronously along the chute 6 on the inner surface of the second bottom strip 2 to ensure the stability of the movement of the two guardrail members 3. Two connecting pieces are fixedly installed at the bottoms of the guardrail members 3. The two connecting pieces are respectively fixedly connected to the screw sleeves 7 and the sliders 5 through two screws, so as to facilitate the disassembly and assembly of the guardrail members 3.

[0028] Working principle: The first bottom bar 1 and the second bottom bar 2 are respectively fixedly installed on both sides of the longitudinal ends of the external lifting seat. In the initial state, the screw sleeve 7 engages with the screw rod 8, and the guardrail member 3 remains stable. Subsequently, the two groups of screw rods 8 are driven to rotate by the two output ends of the bidirectional motor 4. The two groups of screw rods 8 are respectively screwed with the two groups of screw sleeves 7. While the two groups of screw sleeves 7 slide along the two groups of transverse grooves 10 respectively, they respectively provide traction for the two groups of guardrail members 3. The sliders 5 at the bottoms of the two groups of guardrail members 3 slide synchronously along the sliding grooves 6 on the inner surface of the second bottom bar 2, so that the two groups of guardrail members 3 move relative to each other until the distance between the two groups of guardrail members 3 reaches the specified requirement. In this way, while the installation of the guardrail is realized, the guardrail can be conveniently adjusted in position according to the size of the goods. After the first bottom bar 1 and the second bottom bar 2 are placed on both sides of the longitudinal ends of the external lifting seat, a plurality of locking rods 12 are respectively inserted into the inner grooves 11 on the first bottom bar 1 and the second bottom bar 2, and then the fixation of the first bottom bar 1 and the second bottom bar 2 with the lifting seat is completed. Then, a plurality of rubber blocks 9 can be respectively combined with the plurality of inner grooves 11. The interference fit method ensures the stable position of the rubber blocks 9. The rubber blocks 9 will abut against the outer sides of the locking rods 12, so as to limit the loosening of the locking rods 12 through friction.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
