[0034] 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.

[0035] Please refer to Figures 1 to 12 As shown, the present invention provides an embodiment: a template auxiliary transfer device for road tunnel construction, including a device base 1. The bottom of the device base 1 is symmetrically and slidably connected with tracks 2. The top of the device base 1 is provided with a support assembly 3 and a protection assembly 4. The support assembly 3 includes support platforms 31 symmetrically arranged on the top of the device base 1. One of the support platforms 31 is fixedly connected to the device base 1, and the other support platform 31 is slidably connected to the device base 1. The protection assembly 4 includes a driving mechanism 41 and an adjusting mechanism 44. Transmission belts 42 are symmetrically and slidably connected inside the support platforms 31. A number of protection mechanisms 43 are arranged outside the adjusting mechanism 44;

[0036] The driving mechanism 41 includes driving wheels 411 symmetrically and rotatably connected inside the support platforms 31. The driving wheels 411 are meshed with the transmission belts 42;

[0037] The protection mechanism 43 includes a connecting seat 431, a clamping plate 432 and a movable plate 433. The clamping plate 432 is fixedly connected to the side of the connecting seat 431 away from the driving wheel 411. The movable plate 433 is slidably connected between the connecting seat 431 and the clamping plate 432. A connecting shaft 435 is fixedly connected inside the connecting seat 431. The connecting shaft 435 is fixedly connected to the inside of the transmission belt 42;

[0038] The adjusting mechanism 44 includes fixed seats 441 symmetrically and fixedly connected inside the support platform 31. A movable block 442 is slidably connected inside the fixed seat 441, and a third spring 443 is fixedly connected between the movable block 442 and the fixed seat 441.

[0039] In the actual application of the embodiment of the present invention, first, as shown in Figure 2 , Figure 4 and Figure 8 , according to the template size, the support assembly 3 is adjusted. One support platform 31 is fixed to the device base 1, and the other support platform 31 can slide relative to the device base 1. By driving the slidable support platform 31 to move, the distance between the two support platforms 31 is adapted to the width of the template, so as to facilitate carrying the template.

[0040] Subsequently, as shown in Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 and Figure 11 , the driving mechanism 41 in the protection assembly 4 is started. The driving wheels 411 rotate symmetrically inside the support platform 31. Since the driving wheels 411 are engaged with the transmission belt 42, the rotation of the driving wheels 411 drives the transmission belt 42 to slide inside the support platform 31. As the transmission belt 42 slides, the connecting shaft 435 fixedly connected thereto drives the entire protection mechanism 43 to operate. The connecting seat 431, the clamping plate 432 and the movable plate 433 in the protection mechanism 43 work together. The connecting seat 431 moves with the connecting shaft 435. The clamping plate 432 is fixed to one side of the connecting seat 431. The movable plate 433 can slide between the connecting seat 431 and the clamping plate 432, and they extend out of the support platform 31 and approach both ends of the template.

[0041] At the same time, as shown in Figures 9 to 12 , the movable block 442 slidably connected inside the fixed seat 441 in the adjusting mechanism 44 fits with the movable plate 433 under the action of the elastic force of the third spring 443, and drives the movable plate 433 to move and insert between the next connecting seat 431 and the clamping plate 432 through friction, realizing the precise docking between multiple protection mechanisms 43, completing the stable limit protection for both ends of the template, and avoiding the position deviation of the template due to shaking, collision, etc. during the transportation process, ensuring the high efficiency and safety of transportation.

[0042] As shown in Figure 2 , Figure 4 and Figure 6As shown in the figure, the support assembly 3 further includes hydraulic rods 33 symmetrically arranged between the two support platforms 31. The hydraulic rods 33 are fixedly connected to the inside of the support platform 31 on the device base 1. The telescopic ends of the hydraulic rods 33 are fixedly connected to the support platform 31 movably connected to the device base 1. Limiting plates 32 are symmetrically and fixedly connected to the outside of the support platform 31.

[0043] In the actual application of the embodiment of the present invention, when the template size is started, the hydraulic rods 33 in the support assembly 3 are started. As the hydraulic rods 33 expand and contract, the movable support platform 31 is pushed to move, and in cooperation with the fixed support platform 31, the distance between the two is adjusted to adapt to the size of the template, so as to achieve stable loading of the template. At the same time, the limiting plates 32 symmetrically fixed to the outside of the support platform 31 play a role in limiting the movement.

[0044] As Figure 6 、 Figure 7 and Figure 8 As shown in the figure, the driving mechanism 41 further includes a motor 412 fixedly installed on the top of the device base 1. Driving shafts 415 are symmetrically rotatably connected to the top of the device base 1. The driving shafts 415 are fixedly connected to the output shaft of the motor 412 through couplings. An installation shaft 413 is rotatably connected to the inside of the support platform 31. Driving wheels 411 are fixedly connected to the installation shaft 413. A worm gear 414 is fixedly connected to the outside of the installation shaft 413. A worm 416 is fixedly connected to the outside of the driving shaft 415. The worm gear 414 and the worm 416 are meshed with each other.

[0045] In the actual application of the embodiment of the present invention, the motor 412 of the driving mechanism 41 is fixedly installed on the top of the device base 1. After the motor 412 is started, its output shaft rotates, and drives the driving shafts 415 fixedly connected thereto to rotate symmetrically on the top of the device base 1 through the couplings. The worm 416 fixedly connected to the outside of the driving shaft 415 rotates together with the driving shaft 415. Since the worm 416 is meshed with the worm gear 414 fixedly connected to the outside of the installation shaft 413, the rotation of the worm 416 drives the worm gear 414 to rotate, thereby driving the installation shaft 413 to rotate, and the driving wheels 411 fixedly connected to the installation shaft 413 also rotate synchronously. And because the driving wheels 411 are meshed with the transmission belt 42, the rotation of the driving wheels 411 drives the transmission belt 42 to slide inside the support platform 31.

[0046] As Figures 9 to 11 As shown in the figure, sliding blocks 436 are symmetrically and fixedly connected to the outside of the movable plate 433. The sliding blocks 436 penetrate and are slidably connected to the inside of the connecting seat 431. A first spring 437 is fixedly connected between the top of the sliding blocks 436 and the connecting seat 431. Push blocks 434 are slidably connected to the outside of the sliding blocks 436. Second springs 438 are symmetrically and fixedly connected between the push blocks 434 and the connecting seat 431.

[0047] In the practical application of the embodiment of the present invention, the movable plate 433 is slidably connected to the inside of the connecting seat 431 through a slider 436, which not only further ensures the stability of the sliding of the movable plate 433, but also can drive the movable plate 433 to reset after disengaging from the docking with the next protection mechanism 43 through the first spring 437. The push block 434 connected by the second spring 438 can better fit on the outside of the template to ensure the stability of the template limit.

[0048] As Figure 9 , Figure 11 and Figure 12 shown, a lead screw 4392 is rotatably connected to the inside of the connecting seat 431, a clamping block 4391 is slidably connected to the inside of the connecting seat 431, a screw pair drive is formed between the clamping block 4391 and the lead screw 4392, a gear 4393 is fixedly connected to the outside of the lead screw 4392, racks 444 are symmetrically and fixedly connected to the inside of the driving wheel 411, the racks 444 are slidably connected to the inside of the connecting seat 431, and the racks 444 and the gear 4393 are meshed with each other;

[0049] In the practical application of the embodiment of the present invention, during the upward movement of the connecting seat 431, the gear 4393 will be driven to move upward synchronously. When the movable plate 433 moves between the next connecting seat 431 and the clamping plate 432, the gear 4393 meshes with the rack 444. At this time, the continuous movement of the connecting seat 431 will drive the gear 4393 to roll on the rack 444, and the gear 4393 drives the lead screw 4392 to push the clamping block 4391 to move to realize the clamping of the top of the movable plate 433, ensuring the stability of the docking between the protection mechanisms 43.

[0050] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
