Description

Technical Field

[0001] The utility model relates to the technical field of electric poles, in particular to a character spraying device used for concrete electric poles. Background Art

[0002] At present, the transmission line towers must be equipped with line names, pole number plates and necessary safety and protection signs, such as Figure 1 As shown, the pole numbers, road signs, phase color signs, etc. all need to be coated with a white primer first as a prominent background color block on the original cement color of the pole. The painting direction is the main facade of the pole facing the road. After the background color block is drawn, a lettering template is attached to the background and sprayed with black paint, so that the fonts, signs, etc. appear on the white background.

[0003] The problem in the above process is that since the markings on the poles are usually sprayed manually after installation, it is not only necessary to spray at the initial installation, but also when the markings on the poles are covered by randomly pasted advertising tape or the number of poles on the entire line changes, the pole markings need to be re-sprayed. Since the poles are already in a vertical state during spraying, when applying the white primer block and the subsequent black font, the worker needs to manually hold the lettering template, and the other hand or another person holds the paint brush or paint nozzle, making the whole process inconvenient and laborious.

[0004] In addition, dripping paint easily remains on the ground, making the environment near the electric poles dirty, affecting the cleanliness of the municipal environment and greening. At the same time, it is difficult for sanitation workers to clean these dried paint traces, making their work difficult. Utility Model Content

[0005] The utility model provides a spraying device for concrete poles to solve the problems that when spraying marks on poles, sprayers have difficulty in operating the lettering template and the spray paint drips on the ground and is difficult to clean.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is as follows: a spray-on device for concrete poles, comprising a lettering template that can be attached to the surface of the pole, the outside of the pole is detachably connected with a clamp, the top surface of the clamp is provided with a plurality of support rods arranged at intervals along the outer peripheral wall of the pole, the side walls of the support rods are provided with through grooves that can be clamped into the side walls at both ends of the lettering template, the bottom surface of the clamp is provided with a shielding member arranged along the circumference of the pole and covering the bottom of the lettering template, and the inner diameter of the shielding member is in contact with the outer peripheral wall of the pole.

[0007] The basic principle of this solution is: at least two support rods are erected at a position parallel to the surface of the pole through clamps, the distance between the two support rods is the arc length of the lettering template in the circumferential direction, and the through grooves can be used for the left and right end walls of the lettering template to slide from top to bottom into the through grooves of the support rods on both sides respectively, and the left and right end walls of the lettering template are clamped by using the through grooves on the support rods. The staff can spray paint on the lettering template, and the entire lettering device is fixed on the pole before the paint dries. The shielding piece under the clamp can receive dripping paint to prevent the paint from sliding onto the ground.

[0008] The beneficial effects of this program are:

[0009] The existing method of spraying words with handheld lettering templates requires workers to hold and adjust the lettering templates to face the poles, which is laborious and inconvenient to use. The undried paint slides along the poles, drips on the ground and dries, affecting the municipal environment. The present invention provides a support pole to directly clamp the lettering template on the surface of the pole. When multiple different logos are required, multiple lettering templates can be directly clamped into the through grooves and aligned with each other. Workers do not need to laboriously adjust the spacing and alignment. At the same time, the shielding member provided at the bottom can receive the dripping paint during the entire waiting time for the paint to dry. When a large number of poles need to be sprayed, multiple lettering devices are used to quickly position the lettering template for spraying. The clamp-type structure is convenient for disassembly and conversion.

[0010] Furthermore, the support rod includes a first support rod and a second support rod which are arranged in sequence from bottom to top along the height of the electric pole, a slide groove is arranged inside the first support rod for the second support rod to slide up and down, a groove is opened at the lower end of the second support rod with the opening facing the side wall, a limiting structure is arranged in the groove, the limiting structure includes a spring leaf and a small ball arranged at the end of the spring leaf, and a through hole for the small ball to engage is opened on the upper side wall of the first support rod. Two layers of support rods are arranged along the height to meet the installation of lettering templates of different lengths.

[0011] Furthermore, arc strips arranged along the circumferential direction are connected between adjacent support rods at the same height, the arc strips on the first support rod are arranged at intervals along the height of the first support rod, and the first support rod and its arc strips form a first arc frame, the arc strips on the second support rod are arranged at the top end of the second support rod, and the second support rod and its arc strip at the top end form a second arc frame. The second arc frame can be directly pulled out of the first arc frame, which is quick and convenient.

[0012] Furthermore, the clamp is a stainless steel quick-release clamp. The threaded tightening joint is convenient for single-person operation.

[0013] Furthermore, a limit block is provided in the through slot along the height of the through slot, a horizontal spring is connected between the limit block and one of the side walls of the through slot, and the end wall of the lettering template is located between the side of the limit block away from the spring and the side wall of the through slot.

[0014] Furthermore, the shielding member may be made of fan-shaped Oxford cloth or plastic plate; and a semi-annular elastic rubber is embedded on the inner wall of the clamp.

[0015] Furthermore, the lettering template is a flexible and bendable lettering template, such as a polyurethane lettering template, which can better fit the curved surface of the pole and spray the lettering clearly. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following is further described in detail through specific implementation methods:

[0022] The figure marks in the drawings of the specification include: clamp 1, first support rod 2, first arc frame 21, second support rod 3, second arc frame 31, shielding member 4, elastic rubber half ring 5, through groove 6, arc strip 7, slide groove 8, limit structure 9, limit block 10, spring 11, reed 12, small ball 13, through hole 14, lettering template 15.

[0023] The embodiment is basically as shown in the attached Figure 1 To Attachment Figure 5 As shown:

[0024] The first arc frame 21 is located below the second arc frame 31, and the lettering template 15 is located in front of the lettering device, with this direction as a reference.

[0025] A spray-on device for a concrete pole comprises a clamp, a first arc frame 21, a second arc frame 31 and a shielding member 4.

[0026] The clamp 1 adopts a stainless steel quick-release clamp 1, and an elastic rubber half ring 5 is embedded on the inner circumferential wall of the stainless steel quick-release clamp 1. The inner diameter of the elastic rubber half ring 5 is the same as the outer diameter of the pole. The clamp 1 is horizontally sleeved on the outer circumferential wall of the pole, and the inner wall of the elastic rubber half ring 5 is in contact with the outer wall of the pole. The clamp 1 is locked by a threaded connection, and the outer part of the rubber half ring is squeezed by the clamp 1, which increases the static friction between the clamp 1 and the pole, so that the clamp 1 is firmly installed on the pole.

[0027] On the upper surface of one of the clamp petals of the clamp 1, a first arc frame 21 is fixed. The first arc frame 21 includes a plurality of first support rods 2 arranged vertically at intervals along the arc line. In this embodiment, there are three first support rods 2. The left and right first support rods 2 are respectively located at the left and right ends of the semi-arc, and a through groove 6 is opened on the side close to the center of the circle of the left and right first support rods 2. The through groove 6 is used to clamp and fix the lettering template 15 for spraying. In this embodiment, the lettering template 15 is made of a soft plastic sheet, which can be bent arbitrarily and is suitable for bending surfaces and arc surfaces.

[0028] A limit block 10 is installed inside the through slot 6 along the length of the through slot 6. A spring 11 is connected between the limit block 10 and the side wall of the through slot 6. The spring 11 can push the limit block 10 toward the inner wall of the through slot 6, thereby forming a gap with an adjustable width between the limit block 10 and the inner wall of the through slot 6. The gap is used to clamp one side of the engraving template 15 inside the through slot 6.

[0029] The three first support rods 2 are respectively provided with upward sliding grooves 8, so as to slide and connect the second arc frame 31, so that the second arc frame 31 can be raised and lowered, so that the lettering template 15 can also be installed on the second arc frame 31, and the number of marks that can be sprayed on the surface of the pole is increased. The second arc frame 31 includes second support rods 3 corresponding to the first support rods 2, and the second support rods 3 are slidably connected in the sliding grooves 8. The arc bars 7 arranged along the circumferential direction are connected between the adjacent support rods on the same arc frame. The arc bars 7 on the first support rods are arranged at intervals along the height of the first support rod, and the first support rod and its arc bars 7 form a first arc frame, and the arc bars 7 on the second support rods are arranged at the top of the second support rod, and the second support rod and the arc bars 7 at the top form a second arc frame. The arc bars 7 are arranged between the upper ends of the adjacent second support rods 3, and the arc bars 7 connect the second support rods, so that the second arc frame can slide up and down as a whole.

[0030] The end of the second support rod 3 in the middle is provided with a clamping structure, which includes a spring 12 and a small ball 13 at the end of the spring 12. A through hole 14 is opened on the upper side wall of the first support rod 2 in the middle. When the second arc frame 31 moves to the uppermost end, the elastic force of the spring 12 drives the small ball 13 to clamp into the through hole 14, and the entire second arc frame 31 is limited.

[0031] A shielding member 4 arranged along the circumferential direction is fixed to the bottom of the clamp 1. In this embodiment, the shielding member 4 is in the shape of a fan ring covering half of the circumference, and the fan ring covers the bottom of the entire lettering template 15 to prevent undried spray paint from dripping onto the ground. Specifically, the shielding member can be made of a fan-shaped Oxford cloth or plastic plate.

[0032] The specific implementation process is as follows:

[0033] The staff horizontally sleeves the clamp 1 on the pole, pulls the second arc frame 31 upward and clamps it above the first arc frame 21, slides the two ends of the prepared lettering template 15 from top to bottom into the through grooves 6 of the first arc frame 21 and the second arc frame 31, and the lettering template 15 is pressed tightly in the through groove 6 by the limit block 10. The staff then holds a spray gun or paint to paint the lettering template 15. The spraying device can remain stationary before the font is dry. The staff can go to the next pole to install other spraying devices, and then directly remove the clamp 1 of the spraying device after the font is dry.

[0034] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
