Technical Field
[0001] The utility model relates to the technical field of engineering construction machinery, in particular to a gantry crane track grouting device. Background Art
[0002] The construction of port terminal projects often includes the construction of tracks for mobile mechanical equipment such as gantry cranes and grabs. The construction of these tracks includes the installation of steel rails and steel pads. The pouring of cement during the installation of steel pads is an important process. Traditional cement pouring is to mix the cement on site with a special mixer according to the mix ratio required by the design and specifications, and then the mixed cement is manually transported to the part to be poured with the corresponding container, and the cement is poured directly under the steel pad by manual means of the corresponding auxiliary equipment. This pouring method requires that the mixing and pouring of cement be divided into two processes. The mixed cement needs to be transported to the pouring site. In this process, the cement may leak and cause pollution to the surface layer, and there will be a waste of labor during cleaning. In addition, since the mixing equipment cannot be moved, as the pouring progresses, the pouring location and the mixing location are getting farther and farther, and the increase in transportation distance will inevitably increase the labor of the construction personnel. At the same time, the evaporation of water during transportation will cause the mix ratio of the cement during pouring to be inconsistent with that during mixing. Chinese patent 2023107220340 discloses "A grouting machine for the filling layer material at the bottom of ballastless track slab", publication number CN116604693A, the upper part of which is provided with water emulsion equipment, dry material equipment, stirring equipment and electrical control system, the water emulsion equipment stores water and emulsion, the dry material equipment stores the required dry material, the electrical control system controls the water emulsion equipment to meter water and emulsion into the stirring equipment according to the preset ratio parameters, the dry material equipment adds dry material into the stirring equipment, the stirring equipment completes the stirring according to the preset stirring parameters, the bottom of the stirring equipment is provided with a discharge port connected to the pouring equipment, the pouring equipment transports the prepared mortar to the track slab grouting port to complete the pouring operation. The above-mentioned grouting machine has the functions of raw material storage and transportation, batching, stirring, pumping and pouring, and can be transported to the construction site by rail with other construction vehicles, simplifying the construction organization and construction process, improving the construction quality, and solving the problems of preparation and pouring of filling layer materials during track slab replacement. However, the equipment has a complex structure and requires a lot of manpower to operate. The grouting pipe needs to be held in hand at all times during grouting, and it does not have the ability to grout automatically. Due to the obstruction of various mechanical parts on the upper part of the frame machine, grouting cannot be carried out on the inside of the track, affecting the construction efficiency.

At the same time, the row spacing of the grouting can be conveniently adjusted according to the site conditions, and the inside and outside of the track can be conveniently grouted to improve the construction efficiency.

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inner" and "outer" refer to directions away from the geometric center of a specific component.
[0019] like Figure 1 , Figure 2 As shown, the gantry crane track grouting equipment described in the utility model includes a flatbed truck 1 and a mixing chamber 2 loaded on the flatbed truck 1. The flatbed truck 1 is provided with running wheels that can slide on the track 9. A bracket is provided under the mixing chamber 2 so as to suspend the lower end of the mixing chamber 2 and make it leave the bottom plate of the flatbed truck 1, so as to facilitate the grouting operation. A stirring motor 3 is provided at the upper end of the mixing chamber 2. The stirring motor 3 is fixedly mounted on the upper cover of the mixing chamber 2. The upper cover of the mixing chamber 2 is also provided with a feed port 21 with a cover, through which the cement raw material and water can be injected into the mixing chamber 2. The stirring motor 3 is transmission-connected to the stirring blade 22 installed in the inner cavity of the mixing chamber 2. The structure of the mixing chamber 2 and the installation of the stirring blade 22 are existing well-known technologies and will not be described in detail here.
[0020] The left and right sides of the lower end of the mixing chamber 2 are provided with a discharge funnel 4, which can simultaneously pour the cement into the left and right tracks. The discharge funnel 4 is an inclined bucket-shaped structure, and its upper end is welded to the bottom plate of the mixing chamber 2 and communicated with the mixing chamber 2. The lower end of the discharge funnel 4 is rotatably connected to the transfer pipe 5, and the lower end of the transfer pipe 5 is installed with a grouting nozzle 6. The cement flowing out of the mixing chamber 2 passes through the discharge funnel 4 and the transfer pipe 5 under the action of gravity, and finally flows out from the grouting nozzle 6; a driven pulley 51 is fixedly connected to the outer wall of the transfer pipe 5, and the driven pulley 51 is connected to the driving pulley 53 through a transmission belt 52. The driving pulley 53 is installed on the flatbed vehicle 1 through a rotating shaft, and a handle 54 for driving the driving pulley 53 to rotate is installed on the driving pulley 53. The driving pulley 53 is rotated by the handle 54, and when the driving pulley 53 rotates, the driven pulley 51 is driven to rotate through the transmission belt 52, thereby driving the transfer pipe 5 to rotate.
[0021] like Figure 3 As shown, the transfer pipe 5 includes an upper section 55 provided with a driven pulley 51 and connected to the discharge funnel 4, a lower section 56 connected to the grouting nozzle 6, and a middle section 57 connected between the upper section 55 and the lower section 56 and connected to both of them at an obtuse angle. The upper section 55, the middle section 57 and the lower section 56 are an integrated structure. The upper section 55 and the lower section 56 are parallel to each other but not coaxial. The central axes of the two are staggered by a certain distance. The middle section 57 connects the two together, so that the glue flowing out of the discharge funnel 4 can enter the upper section 55 of the transfer pipe 5, move horizontally for a certain distance, and finally be output from the lower section 56; the lower end of the discharge funnel 4 is located above the bottom plate of the flatbed truck 1 and on the inner side of the side of the floor, so that the entire discharge funnel 4 is located within the coverage range of the bottom plate of the flatbed truck 1, and the four corners of the bottom plate of the flatbed truck 1 can play a protective role to prevent the equipment on the flatbed truck 1 from being hit by surrounding objects.
[0022] like Figure 2 , Figure 4 As shown, a semicircular avoidance groove 11 is provided on the side of the bottom plate of the flatbed vehicle 1. The avoidance groove 11 is located directly below the lower port of the discharge funnel 4, and the radius of the avoidance groove 11 is greater than the turning radius of the transfer tube 5 when it rotates. Figure 2 As shown on the left side, the transfer tube 5 rotates, and when its lower section 56 rotates to the outermost side, the grouting range can extend farther to the outer side of the track, meeting the construction requirements; Figure 2As shown on the right side, the adapter tube 5 rotates, and when its lower section 56 rotates to the innermost side, the inner side of the track can be grouted, and at this time the middle section 57 rotates into the avoidance groove 11. The radius of the avoidance groove 11 is large enough to prevent the bottom plate of the mixing chamber 2 from interfering with the movement of the middle section 57. Of course, according to the needs of on-site construction, the position of the lower section 56 can also be set to a position between the outermost side and the innermost side by rotating the adapter tube 5.
[0023] like Figure 3 As shown, a rotatable clamping connection is adopted between the adapter tube 5 and the discharge funnel 4. The adapter tube 5 adopts a corrugated hose or a plastic tube with greater elasticity, which is convenient for bending and forming, and is also convenient for connection with the discharge funnel 4 and the grouting nozzle 6. An annular clamping ring 41 is provided on the outer wall of the lower end of the discharge funnel 4, and a clamping groove matching the clamping ring 41 is provided on the inner wall of the upper section 55 of the adapter tube 5. The upper section 55 is clamped to the lower end of the discharge funnel 4 through the clamping ring and the clamping groove. In this way, while achieving a better sealing effect, the ability of relative rotation between the two is maintained. The connection between the grouting nozzle 6 and the lower section 56 can also adopt this clamping structure with the clamping ring and the clamping groove matching, and of course, a fixed welding structure or other connection structure can also be adopted. The structure of the grouting nozzle 6 is a well-known technology and will not be described in detail here. In addition, in order to facilitate the grouting operation, a valve can also be provided on the discharge funnel 4 or the adapter tube 5 to control the start and end time of grouting. Of course, for the transfer tube 5 and the grouting nozzle 6 made of flexible materials, a clip can also be used to clamp the middle section of the transfer tube 5 or the end of the grouting nozzle 6 to play the role of closing the valve. When it needs to be opened, just remove the clip.
[0024] A trolley handrail 8 is fixedly mounted on the bottom plate of the flatbed trolley 1 , and the driving pulley 53 is located below the trolley handrail 8 .
[0025] When in use, the flatbed cart 1 is placed on the laid track 9, the mortar raw materials and water are injected into the mixing chamber 2 in proportion, the stirring motor 3 is started to stir evenly, the handle 54 is turned to adjust the position of the grouting nozzle 6, and the grouting valve is opened. Under the action of gravity, the stirred mortar is poured into the lower part of the steel pad along the grouting nozzle 6. While pouring the mortar, the construction personnel push the flatbed cart 1 along the track through the cart handrail 8. During the grouting process, the stirring motor 3 can also be turned on to work continuously to accelerate the grouting speed by using the driving force of the stirring blade 22 on the mortar.
[0026] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
