Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0030] In one embodiment of the present invention, see Figures 1 to 13A construction support device comprises a connecting block 2, two groups of symmetrically arranged telescopic support arms 1, a movable seat 9, a lifting and adjusting assembly 45, a rotating drive assembly 46 and an automatic reset assembly 47; two ends of the connecting block 2 are fixedly connected with two groups of symmetrically arranged ball screws 3, the telescopic support arm 1 is provided with two symmetrical groups, a telescopic groove 4 is arranged in one end of the telescopic support arm 1, the ball screw 3 is arranged in the telescopic groove 4, and a nut 5 of the ball screw 3 is fixedly connected to the inner wall of the telescopic groove 4; a sliding groove 7 is arranged in the end of the telescopic support arm 1 away from the telescopic groove 4, and a fixing groove 8 is arranged on one side of the inner wall of the sliding groove 7, and a pressure block 6 is fixedly connected to the end surface of the end of the telescopic support arm 1 away from the telescopic groove 4, and the pressure block 6 is made of rubber. The present invention realizes elastic contact between the telescopic support arm 1 and the support top surface and the support bottom surface through the rubber pressure block 6. , thereby avoiding damage to the structure caused by rigid contact, a floating frame 15 is arranged in the movable seat 9, a fixed frame 16 is fixedly connected in the floating frame 15, a sliding shaft 17 is fixedly connected on the fixed frame 16, the sliding shaft 17 is installed in the sliding groove 7, a pin hole 20 is arranged in the fixed frame 16, the distance between the pin hole 20 and the sliding shaft 17 is the same as the length of the sliding groove 7, a latch bolt 21 is installed in the pin hole 20, the latch bolt 21 passes through the pin hole 20 and the sliding groove 7, a plurality of groups of circumferentially distributed pressure rollers 10 are arranged at the bottom of the movable seat 9, and a rotating notch 19 is arranged in the side wall of the movable seat 9 and the floating frame 15; the lifting and lowering adjustment component 45 is installed between the movable seat 9 and the floating frame 15; the rotating drive component 46 is installed between the telescopic support arm 1 and the connecting block 2; the automatic reset component 47 is installed between the rotating drive component 46 and the ball screw 3; During the transportation process, the present invention can first rotate the movable seat 9, and the movable seat 9 drives the floating frame 15 to rotate synchronously. The movable seat 9 and the floating frame 15 rotate around the sliding shaft 17, so that the telescopic support arm 1 is rotated from a vertical state to a horizontal state. At this time, the pressure block 6 is rotated out of the rotating notch 19, and then the movable seat 9 and the telescopic support arm 1 are moved, so as to adjust the relative position of the sliding shaft 17 in the sliding groove 7, and then the fixed groove 8 is driven to sink by the gravity of the telescopic support arm 1, so that the sliding shaft 17 is stuck in the fixed groove 8, so as to realize the relative limit fixation between the sliding shaft 17 and the telescopic support arm 1 in the horizontal direction (such as Figure 1As shown), at this time, the two groups of telescopic support arms 1 can realize the free movement and transfer of the equipment under the drive of the pressure roller 10. After that, when the equipment is transferred to the installation point, the telescopic support arm 1 can be rotated and erected. At this time, a group of moving seats 9 contact the ground. During the erection process of the telescopic support arm 1, the gravity of the telescopic support arm 1 directly acts on a group of sliding shafts 17 close to the ground, and then through the bevel setting of the fixed groove 8, the gravity of the telescopic support arm 1 is converted into an oblique sliding force between the sliding shaft 17 and the fixed groove 8, so that the sliding shaft 17 slides from the fixed groove 8 to the sliding groove 7, and then when the sliding groove 7 and the pin hole 20 coincide with each other, the latch bolt 21 can be passed through the pin hole 20 and the sliding groove 7 and the nut can be tightened, so that the relative fixed installation between the telescopic support arm 1 and the sliding shaft 17 is realized by the latch bolt 21, so that the telescopic support arm 1 is kept in a vertical state; Then rotate the moving seat 9 on the other set of telescopic support arms 1 and repeat the above operation to complete the deployment and fixation of the moving seat 9 on the other set of telescopic support arms 1 (such as Figure 2 As shown), at this time, the relative height and relative angle between the floating frame 15 and the moving seat 9 can be adjusted according to the different angles and heights between the support top surface and the support bottom surface, and through the mutual cooperation of multiple groups of lifting adjustment components 45, and as the floating frame 15 descends, a group of pressure blocks 6 at the bottom of the telescopic support arm 1 contacts the support bottom surface, and in this process, the present invention can also realize the free movement of the position of the telescopic support arm 1 through the setting of the pressure roller 10, so as to freely adjust the support point of the telescopic support arm 1. When the telescopic support arm 1 is accurately moved to the support point, the connection block 2 and the telescopic support arm 1 can be driven to rotate relative to each other through the rotation drive component 46. The connecting block 2 drives the two sets of ball screws 3 to rotate, and then the two sets of ball screws 3 convert the rotary motion of the connecting block 2 into the linear motion of the nut 5, and the nut 5 drives the two sets of telescopic support arms 1 to move toward each other, so that the two sets of telescopic support arms 1 move and unfold, and while the two sets of telescopic support arms 1 are unfolded, the automatic reset component 47 is compressed and stored, at this time, the pressure block 6 on the top of the other set of telescopic support arms 1 contacts the support top surface, and the automatic reset component 47 is used to limit the connection block 2 and the telescopic support arm 1 in one direction, so as to prevent the two sets of telescopic support arms 1 from shrinking and resetting, and at this time, the two sets of telescopic support arms 1 can be supported by the rotary drive component 46; Then, when the device needs to be taken out, it is only necessary to control the automatic reset component 47 to release the one-way limit between the connection block 2 and the telescopic support arm 1. At this time, the automatic reset component 47 releases the accumulated elastic potential energy and drives the two sets of telescopic support arms 1 to quickly retract and reset through the elastic potential energy; And when the support point needs to be adjusted during the support process, first, it is only necessary to control the two groups of telescopic support arms 1 to shrink slightly through the automatic reset component 47, so that the pressure block 6 on the top of one group of telescopic support arms 1 is separated from the support top surface, and then the relative height between the floating frame 15 and the movable seat 9 is adjusted through multiple groups of lifting and adjusting components 45, so that the other group of telescopic support arms 1 is raised, and then the pressure block 6 at the bottom of the other group of telescopic support arms 1 is separated from the support bottom surface. At this time, the pressure roller 10 contacts the support bottom surface, thereby realizing the rolling contact between the equipment and the support bottom surface, thereby realizing the free transfer of the equipment position, and then repeating the above operation to realize the rapid deployment support of the equipment.

[0031] In one case of this embodiment, see Figure 3 to Figure 8 The rotary drive assembly 46 includes a rotating frame 22, a first bevel gear 28, and a second bevel gear 29; the rotating frame 22 is provided with two groups, and the two groups of rotating frames 22 are symmetrically arranged and rotatably connected to the two ends of the connecting block 2, and two groups of symmetrically arranged mounting seats 26 are fixedly connected between the two groups of rotating frames 22, and a first connecting shaft 27 is rotatably connected in one group of mounting seats 26, and the first bevel gear 28 is fixedly connected to one end of the first connecting shaft 27, and the second bevel gear 29 is arranged between the two groups of rotating frames 22 and fixedly connected to the outer wall of the connecting block 2, and the The first bevel gear 28 and the second bevel gear 29 are meshed with each other; the rotation drive assembly 46 also includes a force adding handle 42; a wrench 41 is fixedly connected to the force adding handle 42, a nut 40 is fixedly connected to the other end of the first connecting shaft 27, and the nut 40 and the wrench 41 cooperate with each other, the two sides of the telescopic support arm 1 are fixedly connected to the sliding positioning cylinder 25, the two sides of the rotating frame 22 are fixedly connected to the fixed mounting blocks 23, the two sides of the fixed mounting blocks 23 are fixedly connected to the sliding positioning rods 24, and the sliding positioning rods 24 are slidably connected to the sliding positioning cylinder 25; The rotary drive assembly 46 firstly performs axial limitation on the rotating frame 22 and the telescopic support arm 1 through the sliding connection between the sliding positioning rod 24 and the sliding positioning cylinder 25. When the rotary drive assembly 46 drives the connecting block 2 to rotate, it is only necessary to insert the wrench 41 on the force-applying handle 42 into the nut 40 and shake the wrench 41. The wrench 41 drives the first connecting shaft 27 to rotate through the cooperation between the nut 40 and the wrench 41. The first connecting shaft 27 drives the first bevel gear 28 to rotate. The first bevel gear 28 drives the second bevel gear 29 to rotate through the mutual engagement with the second bevel gear 29. The second bevel gear 29 drives the connecting block 2 to rotate, thereby driving the connecting block 2 and the rotating frame 22 to rotate relative to each other. Since the rotating frame 22 and the telescopic support arm 1 are axially fixed, the relative rotation between the connecting block 2 and the telescopic support arm 1 is realized.

[0032] In one case of this embodiment, see Figure 10 to Figure 13The lifting and lowering adjustment assembly 45 includes a screw rod 11 and a wire drum 13; the screw rod 11 is provided with multiple groups, one end of the multiple groups of screw rods 11 is rotatably connected to the moving seat 9, the wire drum 13 is threadedly connected to the screw rod 11, and the wire drum 13 is fixedly connected to the mounting shaft 14, and the outer wall of the floating frame 15 is fixedly connected to multiple groups of movable grooves 18, and the mounting shaft 14 is installed in the movable groove 18, and the other end of the screw rod 11 is fixedly connected to the knob 12; The lifting and adjusting component 45 realizes the movable connection between the wire reel 13 and the floating frame 15 by setting the installation shaft 14 and the movable groove 18, thereby preventing multiple groups of wire reels 13 from cooperating with each other to form self-locking. Then, when it is necessary to adjust the relative height between the movable seat 9 and the floating frame 15, it is only necessary to screw the knob 12 to drive the screw rod 11 to rotate. The screw rod 11 is connected with the wire reel 13 through a thread, and the rotational motion of the screw rod 11 is converted into the linear motion of the wire reel 13. At this time, the wire reel 13 drives one side of the floating frame 15 to be lifted and lowered through the mutual cooperation of the installation shaft 14 and the movable groove 18, and then the overall height between the movable seat 9 and the floating frame 15 is relatively adjusted by the rotation of multiple groups of screw rods 11. At the same time, the relative angle between the movable seat 9 and the floating frame 15 can also be adjusted by the individual rotation adjustment of multiple groups of screw rods 11.

[0033] In one case of this embodiment, see Figure 3 to Figure 9 The automatic reset assembly 47 includes a third bevel gear 31, a limiting plate 32, a chuck 34, and a one-way limiting tooth 38; a group of the mounting seat 26 is rotatably connected to the second connecting shaft 30, the third bevel gear 31 is fixedly connected to one end of the second connecting shaft 30, the third bevel gear 31 and the second bevel gear 29 are meshed with each other, the limiting plate 32 is fixedly connected to the other end of the second connecting shaft 30, a sliding cylinder 33 sleeved on the second connecting shaft 30 is provided between the mounting seat 26 and the limiting plate 32, the chuck 34 is fixedly connected to the sliding cylinder 33, and a pressure spring 39 is installed between the mounting seat 26 and the chuck 34; One-way limiting teeth 38 are fixedly connected to one side of the limiting plate 32 close to the chuck 34 and one side of the chuck 34 close to the limiting plate 32, and the two sets of one-way limiting teeth 38 cooperate with each other; A connecting rod 35 is slidably connected in the mounting seat 26, one end of the connecting rod 35 is fixedly connected to the chuck 34, the other end of the connecting rod 35 is fixedly connected to the driving frame 36, and a button 37 is fixedly connected to the driving frame 36. The automatic reset component 47 axially limits the chuck 34 through the sliding connection between the mounting seat 26 and the connecting rod 35, thereby preventing the chuck 34 from synchronously rotating with the limiting plate 32. A stopper 43 is fixedly connected to one end of the ball screw 3 away from the connecting block 2, and a return spring 44 sleeved on the ball screw 3 is arranged between the stopper 43 and the nut 5. When the two sets of telescopic support arms 1 are unfolded, the relative distance between the nut 5 and the stopper 43 is reduced, and then the return spring 44 is compressed by the nut 5 and the stopper 43, so that elastic potential energy is accumulated by the return spring 44. The automatic reset assembly 47 first performs unidirectional rotation limiting between the limit plate 32 and the chuck 34 through the mutual cooperation of the two sets of one-way limiting teeth 38. When the two sets of telescopic support arms 1 are unfolded, the second bevel gear 29 rotates under the drive of the rotation drive assembly 46. The second bevel gear 29 drives the third bevel gear 31 to rotate by mutual engagement with the third bevel gear 31. The third bevel gear 31 drives the second connecting shaft 30 to rotate. The second connecting shaft 30 drives the chuck 34 to rotate. At this time, the chuck 34 and the limit plate 32 are in contact with each other. The chuck 34 is moved to the side away from the limit plate 32 under the action of the one-way limit tooth 38. At the same time, the chuck 34 is always attached to the limit plate 32 under the elastic push of the pressure spring 39. When the telescopic support arm 1 is unfolded, the two groups of telescopic support arms 1 are subjected to compression force, and the compression force on the telescopic support arms 1 is finally converted into the rotation driving force of the limit plate 32. At this time, the limit plate 32 is limited in one direction with the chuck 34 under the mutual cooperation of the two groups of one-way limit teeth 38, thereby preventing the limit plate 32 from rotating and resetting. Then, when the telescopic support arm 1 needs to be retracted and reset, the button 37 only needs to be pressed. The button 37 drives the chuck 34 to move to the side away from the limit plate 32 through the drive frame 36 and the connecting rod 35, and compresses the pressure spring 39. At this time, the two sets of one-way limit teeth 38 lose their cooperation, the limit plate 32 loses its limit, the ball screw 3 loses its axial limit, and the reset spring 44 releases its elastic potential energy, which is converted into the rotational driving force of the ball screw 3 under the action of the ball screw 3, thereby driving the two sets of telescopic support arms 1 to automatically retract and reset; After the contraction and reset is completed, it is only necessary to release the button 37. At this time, the pressure spring 39 loses its compression force, thereby pushing the chuck 34 to move toward the side close to the limit plate 32 again, and the two sets of one-way limit teeth 38 are locked and closed again.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
