DETAILED DESCRIPTION

[0049] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0050] As shown in Figure 1 , Figure 2 , a front windshield spraying and assembling auxiliary tool for a paving machine comprises a base frame 10, which can be moved on the ground under the action of external force; a support structure 20, which is installed above the middle part of the base frame 10 in a space triangular prism shape; four sets of clamping structures 30, which are symmetrically distributed on both sides of the support structure 20; the first end of the clamping structure 30 is fixed on the support structure 20; two sets of door-shaped legs 40, which are symmetrically arranged; the bottom of the door-shaped leg 40 is arranged on the base frame 10, and the top of the door-shaped leg 40 is connected with the second end of the clamping structure 30; the door-shaped leg 40 is used for installing the front windshield assembly; the bottom of the door-shaped leg 40 is provided with a movable support 50 which can move relative to the door-shaped leg 40, and the movable support 50 is used for being installed on the paving machine; a support fixing tool 60, which is clamped in the movable support, and is used for fixing the movable support 50 and the door-shaped leg 40; wherein each set of door-shaped legs 40 is connected with two sets of clamping structures 30.

[0051] Specifically, the base frame 10 can be moved on the ground, and the tool position can be flexibly adjusted according to the actual working condition to adapt to the position and working space of different paving machines, thereby saving the labor of the workers. The support structure 20 is in the shape of a space three-prism and is installed above the middle part of the base frame 10 to provide a stable support base for the entire device; four groups of clamping structures 30 are symmetrically distributed on both sides of the support structure 20, the first end of the clamping structure 30 is fixed on the support structure 20, and the second end of the clamping structure 30 is connected to the top of the door-shaped leg 40, thereby stably connecting the support structure 20 and the door-shaped leg 40 and enhancing the stability of the overall structure; the front windshield assembly 70 includes an upper pasting plate 71 and a glass frame body 72, and the glass frame body 72 is fixed to the upper pasting plate 71 through a hinge.

[0052] The door-shaped leg 40 is installed with the front windshield assembly, and the support structure 20 is in the shape of a space three-prism, so that when the door-shaped leg 40 and the front windshield assembly are sprayed, there is almost no obstruction, and each corner of the door-shaped leg 40 and the front windshield assembly 70 can be sprayed more easily. The two groups of door-shaped legs 40 are symmetrically arranged, and the bottom is installed on the base frame 10, and the bottom is provided with a movable support 50 which can move relatively. During the installation of the front windshield assembly 70 of the paving machine, the movable support 50 is installed on the paving machine, so that the front windshield assembly 70 is stably installed on the paving machine with the aid of the door-shaped leg 40.

[0053] When spraying and assembling, if the movable support 50 is always in a movable state, it is not conducive to the stability of the installation of the front windshield assembly 70 on the door-shaped leg 40, the support fixing tool 60 fixes the movable support 50 and the door-shaped leg 40, ensures the stability of the connection, so that the bottom of the door-shaped leg 40 can be stably arranged on the base frame 10, and after being stabilized, the front windshield assembly is installed on the door-shaped leg 40. Two groups of door-shaped legs 40 are placed on the tool at the same time, and spraying and assembling operations can be performed on the two groups of door-shaped legs 40 and the front windshield assembly installed thereon at the same time.

[0054] In the present application, the tool position can be flexibly adjusted according to actual needs, improving the convenience and universality of operation; in addition, the cooperation between each structure ensures the stability of the device during operation, thereby ensuring the safety of the glass during painting and assembly, so that each corner of the door-shaped leg 40 and the front windshield assembly 70 can be sprayed with paint, ensuring the convenience of painting.

[0055] In a possible implementation, the base frame 10 comprises: four base legs 11, which are rollable relative to the ground; a plurality of cross struts 12, which are arranged in parallel at equal intervals, and the end faces of the two cross struts 12 at the edges are provided with a base leg 11; two vertical struts 13, which are arranged in parallel; each vertical strut 13 is fixed vertically to the top of each vertical strut 13 at the same time; and a reinforcing rod 14, which is fixed vertically to the bottom of the plurality of cross struts 12 at the same time and is located between the two vertical struts 13; wherein the length direction of the cross struts 12 is parallel to the length direction of the door-shaped supporting leg 40, and the bottom ends of the door-shaped supporting leg 40 are arranged on the top faces of the two vertical struts 13, respectively.

[0056] Specifically, the bottom of the four base legs 11 is provided with a roller, which is rollable relative to the ground, facilitating flexible movement of the tooling when the tooling is changed at different sites, without the need for carrying and saving manpower and time. The plurality of cross struts 12 are arranged in parallel at equal intervals to form a stable planar frame, and the equal-interval design makes the force distribution uniform, thereby enhancing the stability and load-carrying capacity of the device. The end faces of the cross struts 12 at the edges are provided with a base leg 11, and the base leg 11 makes the plane where the cross struts 12 are located away from the ground, thereby providing space for the tines during the forklift carrying process. The two vertical struts 13 are arranged in parallel and are fixed vertically to the top of the cross struts 12 to form a stable three-dimensional frame structure, which can resist external force, bear the weight of the components above and external force, and transmit the force to the cross struts 12 and the base legs 11 and then to the ground, thereby ensuring the stability and reliability of the device and also ensuring that the tooling is fixed firmly left and right and front and back. The reinforcing rod 14 is fixed vertically to the bottom of the plurality of cross struts 12 and is located between the two vertical struts 13, connects the cross struts 12 to form a compact overall structure, prevents the cross struts 12 from deforming and displacing, and also can share the pressure of the vertical struts 13 to improve the load-carrying capacity of the device. The cross struts 12 and the vertical struts 13 are both rectangular tubes and have a certain thickness in the resin direction. Each vertical strut 13 is fixed vertically to the top of each vertical strut 13 at the same time, and the bottom ends of the door-shaped supporting leg 40 are arranged on the top faces of the two vertical struts 13, respectively. Overall, the space between the two vertical struts 13 is a downwardly recessed surface, and the surface is the surface where the top faces of the cross struts 12 are located. Due to the existence of the recessed surface, when the door-shaped supporting leg 40 and the front windshield assembly are sprayed, the bottom of the windshield is not easy to collide with the top face of the cross struts 12 when it is necessary to push the windshield away. The base legs 11, the cross struts 12, the vertical struts 13, and the reinforcing rod 14 are all rectangular tubes.

[0057] In a possible implementation, the base frame 10 further comprises: a plurality of rows of clamping rings 15, each row of clamping rings 15 comprising a plurality of clamping rings 15, the inner dimensions of the clamping rings 15 matching the dimensions of the tines of the forklift, and the number of rows of clamping rings 15 matching the number of tines of the forklift; wherein each clamping ring 15 in each row of clamping rings 15 is mounted equidistantly on the bottom face of a different cross strut 12.

[0058] Specifically, the inner size of the clamping ring 15 matches the teeth of the forklift and the number of columns corresponds, so that the teeth of the forklift can be closely matched with the clamping ring 15, the connection is reliable, and the forklift can stably fork the tooling through the clamping ring 15. The clamping ring 15 is installed equidistantly on the bottom surface of different cross struts 12, so that the force applied by the forklift can be evenly distributed to each cross strut 12.

[0059] In a possible implementation, the support structure 20 comprises: two sets of triangular chassis 21, which are symmetrical; the bottom surface of each set of triangular chassis 21 is installed on the top surface of a vertical strut 13; and a cross beam 22, both ends of which are fixed to the top end of each set of triangular chassis 21, and the cross beam 22 is parallel to the cross strut 12.

[0060] Specifically, as shown in Figure 3 each set of triangular chassis 21 comprises two inclined struts, the bottom ends of which are welded to a vertical strut 13, and the top ends of which are welded together, so that the two inclined struts and the part of the vertical strut 13 between the bottom ends of the two inclined struts form a triangular frame. The cross beam 22 is fixed at both ends to the top end of the triangular chassis 21, and forms a stable frame with the triangular chassis 21 and the vertical strut 13, thereby enhancing the rigidity of the tooling. The two sets of triangular chassis 21 and the cross beam 22 form a stable support system. In addition, the angle of the inclined struts further determines the distance between the front windshield assembly 70 and the ground, and the inclined struts are symmetrical on the left and right. The inclined struts and the cross beam 22 are rectangular tubes.

[0061] In a possible implementation, the clamping structure 30 comprises: a fixed rod 31, the first end of which is fixed vertically to the cross beam 22; and a movable fork 32, the first end of which is overlapped on the second end of the fixed rod 31, and the second end of which is connected to the door-shaped leg 40.

[0062] Specifically, as shown in Figure 2 , Figure 3 the first end of the fixed rod 31 is fixed vertically to the cross beam 22, and the other end is connected to the movable fork 32, thereby connecting the cross beam 22 and the movable fork 32. The length of the fixed rod 31 fixed vertically to the cross beam 22 ensures that there is a proper distance between the front windshield assemblies in the two sets of door-shaped legs 40 on both sides, so that the spray gun used by the worker can spray each position surface of the door-shaped leg 40 and the front windshield assembly therein during the paint spraying process. During installation, the tooling 60 is first fixed with the support to fix the movable support 50 relative to the door-shaped leg 40, and then the door-shaped leg 40 is connected to the second end of the movable fork 32, at this time the movable fork 32 bears the weight of the door-shaped leg 40, and the first end of the movable fork 32 connected with the door-shaped leg 40 is connected to the second end of the fixed rod 31 by overlapping, so that the installation process is more convenient. The fixed rod 31 is a rectangular tube.

[0063] In a possible implementation, the movable fork 32 comprises a connecting rod 321, a lap joint 322 arranged at a first end of the connecting rod 321, the lap joint 322 being configured to be connected to a second end of the fixed rod 31, and a fixed head 323 arranged at a second end of the connecting rod 321, the fixed head 323 being connected to the door-shaped leg 40.

[0064] Specifically, as shown in Figure 2 、 Figure 3 the lap joint 322 is arranged at the first end of the connecting rod 321 and is configured to be connected to the second end of the fixed rod 31. The lap joint 322 is quickly and stably connected to the fixed rod 31, and the installation is convenient. The fixed head 323 is arranged at the second end of the connecting rod 321 and is connected to the door-shaped leg 40, so that the movable fork 32 is stably connected to the door-shaped leg 40. The connecting rod 321, the lap joint 322, and the fixed head 323 are cooperated with each other, so that the movable fork 32 is stably connected to the fixed rod 31 and the door-shaped leg 40, and the overall stability of the device is ensured. The connecting rod 321 is a rectangular tube.

[0065] In a possible implementation, the lap joint 322 comprises two groups of first side plates 3221, the two groups of first side plates 3221 are arranged oppositely, and the size between the two groups of first side plates 3221 is greater than the width size of the second end of the fixed rod 31; the first side end surface of the two groups of first side plates 3221 is open; a cover plate 3222 is connected to the top end surface of the two groups of first side plates 3221; and a sealing plate 3223 is perpendicular to the cover plate 3222 and is connected to the second side end surface of the two groups of first side plates 3221; wherein, when the lap joint 322 is lapped on the second end of the fixed rod 31, the top surface of the second end of the fixed rod supports the cover plate 3222, the two groups of first side plates 3221 are respectively arranged on the two sides of the second end of the fixed rod 31, and the sealing plate 3223 is opposite to the end surface of the second end of the fixed rod 31.

[0066] Specifically, as shown in Figure 2 、 Figure 3As shown, the size between the two groups of the first side plates 3221 is greater than the width size of the second end of the fixed rod 31, and the first side end face of the first side plate 3221 is open, which ensures that there is an adjustable margin during assembly, so that the second end of the fixed rod 31 can be easily inserted between the two groups of the first side plates 3221 from the opening. When the lap joint 322 is lapped on the second end of the fixed rod 31, the top surface of the second end of the fixed rod 31 supports the cover plate 3222, and the two groups of the first side plates 3221 are respectively located on the two sides of the second end of the fixed rod 31, forming effective limiting of the second end of the fixed rod 31. This limiting action can prevent unnecessary displacement of the movable fork 32 in the horizontal direction, ensuring the stability of the connection between the movable fork 32 and the fixed rod 31. The lap joint 322 is lapped with the second end of the fixed rod 31 through the open first side plate 3221, and this lapping installation method is simpler and more convenient. During installation, the operator only needs to align the opening between the two groups of the first side plates 3221 with the second end of the fixed rod 31, and the preliminary lapping can be completed, which greatly saves labor and facilitates assembly.

[0067] In a possible implementation, first threaded holes are formed on the two groups of the first side plates 3221, a second threaded hole is formed on the second end of the fixed rod 31, and the clamping structure 30 further comprises: a first fixing screw 33, the first fixing screw 33 penetrating the two groups of the first side plates 3221 and the second end of the fixed rod 31, and the first fixing screw 33 being used for fixing the two groups of the first side plates 3221 and the second end of the fixed rod 31 by penetrating the first threaded holes and the second threaded hole.

[0068] Specifically, as shown in Figure 2 , Figure 3 the first threaded holes on the two groups of the first side plates 3221 and the second threaded hole on the second end of the fixed rod 31 cooperate with each other to form accurate positioning and guidance, so that the first fixing screw 33 can accurately penetrate and connect them, and the close threaded cooperation relationship enhances the stability of the connection between the lap joint 322 and the fixed rod 31, preventing loosening and disconnection.

[0069] In a possible implementation, the top of the door-shaped leg 40 is provided with two groups of hanging ears 41, a group of third threaded holes is formed on each group of the hanging ears 41, and the fixed head 323 comprises: two groups of the pasting plates 3231, the two groups of the pasting plates 3231 being respectively welded on the two sides of the second end of the connecting rod 321, a plurality of groups of fourth threaded holes being formed on the pasting plate 3231 along the length direction, and each group of the fourth threaded holes penetrating the two pasting plates 3231 and the second end of the connecting rod 321; and a second fixing screw 3232, the second fixing screw 3232 being used for connecting the second end of the connecting rod 321 and the hanging ear 41 by penetrating a group of the third threaded holes and a group of the fourth threaded holes.

[0070] Specifically, as shown in Figures 1-4As shown, the third threaded holes on the two groups of hanging ears 41 at the top of the door-shaped legs 40 are matched with the fourth threaded holes on the two groups of sticking plates 3231 in the fixing head 323, and the second fixing screws 3232 are used as the connecting medium to pass through a group of third threaded holes and a group of fourth threaded holes to tightly connect the second end of the connecting rod 321 and the hanging ears 41, so that a stable and adjustable connecting structure is formed between the movable fork 32 and the door-shaped legs 40, which on the one hand ensures that the movable fork 32 can be reliably installed on the door-shaped legs 40 to provide stable support for the entire device, and on the other hand, the design of multiple threaded holes makes the connecting position adjustable, and the position of the movable fork 32 relative to the door-shaped legs 40 can be flexibly adjusted according to actual work requirements, that is, the inclination angle of the door-shaped legs 40 relative to the ground is adjusted. In addition, the two sides of the second end of the connecting rod 321 are welded with the sticking plates 3231 to ensure that the connecting rod 321 has sufficient strength when bearing the front windshield assembly tension.
