Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of highway precast beam construction technology, and specifically relates to an automatic chiseling device for the flange plate of a highway precast beam. BACKGROUND

[0002] At present, precast beams are used as bridge spans in the design of highway construction projects, and precast beams are generally precast in ring-shaped beam yards and ordinary beam yards at home and abroad. The flange plate of the precast beam is chiseled manually in the initial stage, and the flange plate is densely reinforced, so the chiseling is difficult, the manual usage rate is high, and the chiseling quality is uncontrollable.

[0003] With the development of the industry, some highway beam yards use the method of pre-embedding a grout stopping belt at the flange plate of the precast beam to replace chiseling, and after the precast beam is demolded and the grout stopping belt is removed, a pitted surface will be formed at the flange plate, so that the area of the fusion of new and old cement is wider. When the method is used for construction, the mortar layer still exists on the surface of the flange plate, which does not meet the provisions in the "Highway Bridge and Culvert Construction Technical Specification" JTG / T 3650-2020 that the smooth surface layer and weak layer of the concrete surface at the construction joint should be chiseled off, and the minimum depth of chiseling should be not less than 8mm.

DETAILED DESCRIPTION

[0033] To make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below. Obviously, the described embodiment is a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0034] As shown in Figure 4 A highway prefabricated beam flange plate automatic chiseling device, comprising:

[0035] A mechanical arm moving platform 4 moves along the prefabricated beam flange plate 1.

[0036] A mechanical arm base 5 is fixed on the mechanical arm moving platform 4.

[0037] A mechanical arm large arm 6 is installed on the mechanical arm base 5 at the lower end.

[0038] A mechanical arm small arm 7 is hingedly connected to the upper end of the mechanical arm large arm 6 at one end, and the mechanical arm small arm 7 is arranged horizontally.

[0039] A shot blasting device 8 is installed at the other end of the mechanical arm small arm 7.

[0040] Specifically, the impact baffle 9 is arranged above the shot blasting device 8, the impact baffle 9 is an L-shaped structure, and the shot blasting device 8 is fixed on the mechanical arm small arm 7. The impact baffle 9 is made of a 0.5mm-thick steel plate, which can block the randomly bounced steel shots and facilitate recycling.

[0041] Specifically, the steel shot recycling box 3 is arranged on one side of the prefabricated beam flange plate 1 close to the mechanical arm moving platform 4, and the steel shot recycling box 3 is arranged below the shot blasting device 8.

[0042] Specifically, the steel shot recycling box 3 comprises a recycling box body 3.1, an opening is arranged on the upper side of the recycling box body 3.1, and a layer of damping material 3.2 is arranged on the inner side of the recycling box body 3.1.

[0043] The recycling box body 3.1 is made of a 1cm-thick steel plate, and the damping material 3.2 is made of 2cm-thick rubber.

[0044] Specifically, the mechanical arm moving platform 4 comprises:

[0045] a platform plate 4.3;

[0046] a track wheel 4.1 installed at the bottom of the platform plate 4.3, and the track wheel 4.1 is driven by a walking motor 4.2.

[0047] Specifically, the mechanical arm moving platform 4 moves along the steel rails 2.1 arranged on both sides of the prefabricated beam flange plate 1, and the steel rails 2.1 are arranged on the track base 2.

[0048] Specifically, as shown in Figure 5 the shot blasting device 8 comprises:

[0049] a motor 8.1;

[0050] a coupling disc 8.2 installed on the output shaft of the motor 8.1;

[0051] a shot separating wheel 8.6 installed at the center of the coupling disc 8.2 and rotating with the coupling disc 8.2;

[0052] an impeller 8.8 coaxially arranged with the shot separating wheel 8.6 and rotating with the coupling disc 8.2;

[0053] a roller 8.4 fixed on the coupling disc 8.2 and rotating with the coupling disc 8.2;

[0054] a shot blasting pipe 8.7 arranged outside the roller 8.4.

[0055] Specifically, the electric motor 8.1 is mounted on the end of the robotic arm 7 via a motor mount 8.1. The electric motor 8.1 drives the coupling disc 8.2 to rotate, which in turn drives the shot distribution wheel 8.6, impeller 8.8, and drum 8.4 to rotate. The shot distribution wheel 8.6, impeller 8.8, and drum 8.4 are connected together via an external linkage disc 8.5. Under the action of the shot distribution wheel 8.6 and impeller 8.8, steel shot is ejected from the shot blasting tube 8.7.

[0056] When using it, step one: install the automatic flanging device;

[0057] like Figure 1 As shown, the precast beam flange plate 1 is equipped with longitudinally moving steel rails 2.1 and rail bases 2 on both sides, and an automatic roughening device is installed on each side.

[0058] Step 2: The position and angle of the shot peening equipment and the position and angle of the steel shot recovery device are automatically adjusted by the robotic arm 6 and robotic arm 7.

[0059] like Figure 2 As shown, a model analysis of the shot peening and roughening equipment is performed. The equipment uses a robotic arm to adjust the position of the roughening equipment to an angle of 45-55° with the horizontal line of the flange plate before shot peening. The steel shot is reflected downwards from the concrete surface of the flange plate, creating pits on the concrete surface.

[0060] Step 3: As Figure 3 As shown, after the equipment angles are adjusted to the correct positions, it automatically performs shot peening at the preset shot peening speed to roughen the surface. Simultaneously, a recovery device collects the blasted steel shot. During operation, the equipment moves longitudinally at a uniform speed on the longitudinal track according to the preset running speed and stroke, automatically roughening the precast beam flange.

[0061] The equipment roughens the flange by adjusting the shot peening density, shot peening speed, and longitudinal travel speed. After the reflective pits become dense enough, a roughened surface is formed, and the task is completed.

[0062] After the precast beam flange is roughened to the required level, the steel shot in the recycling equipment is transferred to the shot blasting equipment for future use.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
