Technical Field

[0001] The utility model relates to the technical field of engineering pile foundation construction, in particular to a rain shielding device for an automatic welding mechanical arm for prefabricated pile connection. Background Art

[0002] At present, welding is still the most commonly used connection for precast piles in pile foundation construction. The quality of welding is particularly important for pile foundation projects. The quality of welding is limited by the welder's operating skills and welding working environment. Automatic welding technology is applied to the welding of precast piles, which solves the impact of uneven welder skills on welding quality.

[0003] However, the pile connection construction at the construction site is mainly carried out in an open-air environment, which cannot be fully protected from rain. In order to prevent rainy days from affecting the construction period and welding quality of the welded pile connection, effective rain shielding measures must be taken during the welding construction on rainy days. In recent years, some prefabricated pile welding rainproof devices have appeared on the market, some of which are cumbersome and inconvenient to install, and some have poor rain protection effects. In order to solve the problem of rain protection for the prefabricated pile connection welding robot arm, the present application proposes a device that is easy to install and low-cost, which can effectively solve the problem of rain protection for the prefabricated pile connection welding robot arm. Utility Model Content

The base sleeve is positioned on the precast pile, and the rain cover plate is tilted on the precast pile to tighten the contact surface between the rain cover plate and the outer surface of the precast pile, thereby ensuring the sealing between the groove of the rain cover plate and the precast pile to prevent rainwater from flowing in. The entire device has a stable structure, is safe and reliable, and is simple and convenient to install and disassemble.

[0007] Preferably, at least one elastic member is further included, one end of which is connected to the rain cover plate, and the other end of which is connected to the base or the support plate.

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] like Figures 1 to 5As shown, a rain shielding device for an automatic welding robot arm for prefabricated pile connection comprises a base 1, a rain shield plate 2 and at least one elastic member 3; the base 1 is provided with a slot 10 with an opening for the prefabricated pile to be inserted laterally; the upper end of the base 1 is connected with a support plate 11; the rain shield plate 2 is located above the base 1 and above the prefabricated pile connection weld, the rain shield plate 2 can be connected to the support plate 11 rotatably up and down, and the base 1 is provided with a clamping mechanism for clamping on the peripheral wall of the prefabricated pile; when the rain shielding device is installed on the prefabricated pile, the prefabricated pile is located in the slot 10, the clamping mechanism is clamped on the prefabricated pile, and one end of the rain shield plate 2 is pressed against the peripheral wall of the prefabricated pile, so that the rain shield plate 2 keeps a state of gradually tilting downward from one end close to the prefabricated pile to one end away from the prefabricated pile, and the tilt angle of the rain shield plate 2 is 25-35°. The tilt angle is conducive to the drainage of rainwater, and the tilted installation is also further conducive to the stability and firmness of the entire device. A welding space 6 is formed between the rain cover plate 2 and the base 1, into which a welding gun can enter, and the welding space 6 facilitates the operation of the automatic welding machine. The upper end of the elastic member 3 is connected to the rain cover plate 2, and the lower end of the elastic member 3 is connected to the base 1. When the rain shielding device is installed on the prefabricated pile, the elastic member 3 is used to provide elastic force so that one end of the rain cover plate 2 has a tendency to rotate downward. The base 1 is set and positioned on the prefabricated pile, and the rain cover plate 2 is tilted and set on the prefabricated pile by the elastic member 3. The contact surface between the rain cover plate 2 and the outer surface of the prefabricated pile is pressed by the tension of the elastic member 3, so that the whole device is in a locked state, maintaining the stability of the whole device, thereby ensuring the sealing between the card slot 10 of the rain cover plate 2 and the prefabricated pile, preventing rainwater from flowing in, and the whole device has a stable structure, is safe and reliable, and is simple and convenient to install and disassemble.

[0025] like Figures 1 to 3 As shown, the base 1 is a U-shaped rod, and the U-shaped section 101 in the middle of the U-shaped rod forms a slot 10. The two parallel rods of the U-shaped rod form a clamping mechanism. When the rain shielding device is installed on the prefabricated pile, the base 1 is clamped on the prefabricated pile by the two parallel rods. The U-shaped rod with elastic clamping force further increases the friction between the base 1 and the prefabricated pile, thereby ensuring the stability of the base 1. The support plate 11 is two vertical rods, and the two vertical rods are formed by bending the free ends of the parallel rods upward. The structural strength and production convenience are further improved by the one-piece molding setting. The U-shaped section 101 in the middle of the base 1 is wrapped with an anti-skid rubber strip 4. When the device is assembled on the prefabricated pile, the anti-skid rubber strip 4 is tightly against the outer peripheral wall of the prefabricated pile. The anti-skid rubber strip 4 further increases the friction between the two, thereby ensuring the stability and connectivity of the base 1.

[0026] like Figures 1 to 5As shown, a groove 21 with an opening for the prefabricated pile to be inserted transversely is provided at one end of the rain cover plate 2. The bottom of the groove 21 is an arc surface. When the rain shielding device is installed on the prefabricated pile, the prefabricated pile is located in the groove 21, and the arc surface is pressed against the peripheral wall of the prefabricated pile. The groove 21 facilitates better matching and close contact with the peripheral wall of the prefabricated pile, further improving the fit, thereby ensuring the sealing when the two are connected. An embedding opening 211 is provided at the bottom of the groove 21, and an elastic sealing strip 5 is embedded in the embedding opening 211; the elastic sealing strip 5 can be more closely combined with the outer surface of the pile, ensuring the sealing between the arc recess 21 and the prefabricated pile, and preventing the inflow of rainwater. The cross section of the elastic sealing strip 5 is convex, and the two sides of the elastic sealing strip 5 are embedded in the embedding opening 211, and the middle part of the elastic sealing strip 5 extends to the outside of the embedding opening 211. After the device is fixed, the middle part of the elastic sealing strip 5 is against the outer peripheral wall of the prefabricated pile. When the device is assembled on the prefabricated pile, the elastic sealing strip 5 is pressed between the groove 21 and the prefabricated pile. The elastic sealing strip 5 ensures the sealing between the arc notch and the prefabricated pile to prevent the inflow of rainwater.

[0027] like Figure 1 As shown, the rain cover plate 2 is detachably and rotatably connected to the support plate 11, and the top of the support plate 11 is provided with an arc-shaped concave surface 111; the bottom of the rain cover plate 2 is provided with a rotating shaft 22; when connected, the rotating shaft 22 is rotatably connected in the arc-shaped concave surface 111. The detachable and rotatable connection is achieved through the arc-shaped concave surface 111 and the rotating shaft 22, which facilitates rotation positioning while ensuring connection stability.

[0028] like Figure 1 As shown, the elastic member 3 is a tension spring. There are two elastic members 3, and the two elastic members 3 are symmetrically arranged on both sides of the opening of the card slot 10; the first hooks 12 are symmetrically arranged on the top of both sides of the base 1; the second hooks 23 are symmetrically arranged on both sides of the bottom of the rain cover plate 2; the lower end of the elastic member 3 is sleeved on the first hook 12, and the upper end of the elastic member 3 is sleeved on the second hook 23 on the same side as the first hook 12, and the elastic member 3 is tilted from top to bottom from the side away from the precast pile to the side close to the precast pile. The installation and fixation of the elastic member 3 are facilitated by the arrangement of the first hook 12 and the second hook 23, and the tilted arrangement further facilitates the clamping of the rain cover plate 2 on the precast pile. The elastic sealing strip 5 of the rain cover plate 2 is pressed by the tension of the elastic member 3 to make it contact with the outer surface of the precast pile, so that the whole device is in a locked state to maintain the stability of the device.

[0029] When the device is assembled on the precast pile, the base 1 is limited on the outer peripheral wall of the precast pile by the slot 10, and is clamped on the precast pile by two parallel rods on the base 1. The rotating shaft 22 on the rain cover plate 2 is installed in the arc-shaped concave surface 111 of the support plate 11, and rotates downward under the action of the two elastic members 3 until the side wall of the elastic sealing strip 5 on the groove 21 on the rain cover plate 2 is tightly against the outer peripheral wall of the precast pile.

[0030] To sum up, the advantage of the utility model is that it can effectively solve the problem of automatic welding machine mechanical arm shielding rain during prefabricated pile welding construction in rainy days, prevent rainwater from flowing into the welding area to damage the weld quality and affect the welding effect. The whole device has a stable structure, is safe and reliable, and is simple and convenient to install and disassemble.
