Description

Technical Field

[0001] The invention relates to the field of shotcrete reduction box assembly, in particular to a concrete shotcrete reduction box assembly equipment tooling. Background Art

[0002] Shotcrete machine is a kind of equipment widely used in construction, tunnels, bridges and other fields. It is mainly used for spraying concrete, cement slurry and other materials. The main feature of the shotcrete machine is that it can complete the spraying operation efficiently and quickly, and the spraying amount and spraying angle can be adjusted according to needs. The shotcrete machine reduction box is an important part of the shotcrete machine, which is mainly used to reduce speed and transmit power. The shotcrete machine reduction box usually adopts gear transmission, which has high transmission efficiency and stability.

[0003] The existing assembly process of the bearing and gear shaft of the reduction box of the shotcrete machine with the box body and the box cover is to assemble the bearing and gear shaft by hammering with a hammer or a copper rod. Its objective disadvantages are as follows:

[0004] 1. The labor intensity of the assembly workers is high. The existing assembly process of the gear shaft of the reduction gearbox with the box body and the box cover is to assemble the bearings and gear shafts by hammering with a hammer or a copper rod. Because the bearings, the box body and the box cover, as well as the bearings and the gear shafts, are all interference fit, the assembly resistance is very large, which requires the assembly workers to pay a lot of physical labor;

[0005] 2. Low assembly efficiency. Because the assembly is done by manual tapping, the same bearing needs to be tapped multiple times before it can be installed in the required position, so its assembly efficiency is relatively low;

[0006] 3. The quality is not easy to guarantee and there are quality risks. The current production process is to assemble by hammering with a hammer or a copper rod. The knocking position is easy to deviate, which makes the bearing unevenly stressed and prone to installation deviation. Excessive knocking force can easily damage the bearing or even crack it. If the bearing is cracked and not replaced, it will cause quality risks to the reducer. Therefore, in order to ensure the quality, the installation difficulty is further increased;

[0007] 4. The production and assembly costs are high. The existing assembly process results in relatively low assembly efficiency, and now the labor cost is increasing, so the production and assembly costs are also relatively high. Summary of the invention

[0008] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a concrete shotcrete machine reducer assembly equipment tooling to solve the problems of high strength, low efficiency, quality risks and high cost in the manual tapping assembly of bearings and gear shafts proposed in the background technology.

[0009] In order to solve the above technical problems, the present invention provides the following technical solutions: a concrete shotcrete machine reducer assembly equipment tooling, including a tooling frame, a pair of rail wheel guides extending from both sides are provided inside the tooling frame, the pair of rail wheel guides are rollingly connected to a plurality of rail wheel tooling trolleys on which a reducer box body can be placed in a limited position, one side of the tooling frame is provided with a plurality of pressing tools that can adapt to bearings of different sizes, the upper and lower parts of the tooling frame are respectively provided with an upper cylinder and a lower cylinder for pressing down and pressing up the assembled bearings, and one side of the tooling frame is also provided with a hydraulic reversing valve for controlling the upper cylinder and the lower cylinder.

[0010] Preferably, a pair of the rail wheel guide rails are respectively fixed with a plurality of supporting legs at the bottom, and the pair of the rail wheel guide rails are respectively fixed and fitted to both sides of the interior of the tooling frame through the outer side.

[0011] Preferably, the rail-wheel tooling trolley includes a moving frame, rail wheels and a limit clamp seat, the moving frame is a rectangular frame, the rail wheels are provided with at least six and are symmetrically distributed on both sides of the bottom long side of the moving frame, the rail wheels are engaged with the rail wheel guide rails and roll, the limit clamp seat is fixed on the top of the moving frame and can limit and fix the housing of the reduction box, and two hooks are fixed on both sides of the short side of the moving frame.

[0012] Preferably, an upper support frame is fixed to the top of the tooling frame, the upper oil cylinder is fixed to the upper support frame with the cylinder body facing downward, and the end of the hydraulic rod of the upper oil cylinder passes through the bottom of the upper support frame and is fixed with an upper pressure head.

[0013] Preferably, the tooling frame is also fixed with a lower support frame located below the rail wheel guide rail, the lower oil cylinder is fixed to the lower support frame with the cylinder body facing upward, the end of the hydraulic rod of the lower oil cylinder passes through the top of the lower support frame and is fixed with a pressure plate, the top of the pressure plate is fixed with a lower pressure head, and four positioning columns are arranged in a rectangular array on the periphery of the lower pressure head.

[0014] Preferably, a mounting plate is vertically fixed on one side of the tooling frame above the rail wheel guide rail, and the hydraulic reversing valve is fixed on one side of the mounting plate. The hydraulic reversing valve is provided with an oil inlet, an oil outlet and four oil control ports, and the hydraulic reversing valve is also provided with a relief valve and two handles.

[0015] Preferably, a placement rack is fixed on one side of the tooling rack located above the rail wheel guide rail, and a plurality of the press-fitting tools are placed in the placement rack.

[0016] Preferably, a hydraulic oil tank and a hydraulic oil pump motor for driving the upper oil cylinder and the lower oil cylinder are fixed on one side of the tooling frame below the rail wheel guide rail.

[0017] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0018] 1. Greatly reduce the labor intensity of workers. The gearbox is hoisted by a crane to the tooling frame of the assembly equipment. The hydraulic oil pump motor provides power. The press-fitting of the bearings and gear shafts requires manual operation of the equipment. The hydraulic cylinder then presses the bearings into the specified position of the gearbox through the corresponding bearing press-fitting tool, which greatly reduces the labor intensity of workers.

[0019] 2. Further improve assembly efficiency. Since the press-fitting of the bearings and gear shafts of the reduction box is provided by the hydraulic system, the workpieces can be pressed into place at one time, thus further improving assembly efficiency.

[0020] 3. The assembly quality is guaranteed. The pressure of the bearings and gear shafts of the reduction box is provided by the hydraulic system, which avoids the hidden danger of cracks in the bearings due to metal impact, thus ensuring the assembly quality.

[0021] 4. The production and assembly costs are reduced. The gearbox assembly equipment is used to press the gears and gear shafts, which reduces the labor intensity of workers and improves production efficiency, thereby reducing the production cost of the shotcrete machine.
