Description

TECHNICAL FIELD

[0001] The present application relates to the field of concrete hollow products, in particular to an automatic production system of a telegraph pole and a pipe pile. BACKGROUND

[0002] Early telegraph poles are all started from wooden poles, even including high-voltage line poles with not too high voltage. Later, with the development of reinforced concrete and the exploration of technology, reinforced concrete tapered cement poles and equal-diameter cement telegraph poles are manufactured by using the principle of centrifugal force to replace most of the wooden poles. The cement telegraph poles are firm, durable, corrosion-resistant, temperature-difference-resistant, high-strength and crack-resistant.

[0003] In the production process of the concrete telegraph pole, the mixed concrete needs to be injected into a steel mold formed by buckling an upper mold and a lower mold to facilitate feeding and taking out the finished product, and then the steel mold is driven to rotate at high speed to form the telegraph pole in the middle of the concrete material, and finally steam is used for maintenance. In order to make the formed telegraph pole more easily separated from the steel mold, the upper mold and the lower mold of the steel mold need to be sprayed with a release agent before buckling.

[0004] According to the related technology in the above, the inventor believes that the opening direction of the upper mold is downward, and the opening direction of the lower mold is upward, so two different spraying mechanisms are needed to spray the release agent on the upper mold and the lower mold respectively, which uses more equipment, has a longer production process and higher cost. SUMMARY

[0005] In order to reduce the production cost of the telegraph pole, the present application provides an automatic production system of a telegraph pole and a pipe pile.

[0006] The automatic production system of the telegraph pole and the pipe pile provided by the present application adopts the following technical solution:

[0007] The automatic production system of the telegraph pole and the pipe pile comprises an automatic mold opening and closing mechanism and an oil spraying mechanism. The automatic mold opening and closing mechanism comprises an upper mold support seat and a lower mold support seat. A turnover mechanism for turning over the upper mold to the lower mold support seat is arranged on the upper mold support seat. The oil spraying mechanism comprises an oil pipe support and a liquid storage tank. An oil spraying pipe connected with the liquid storage tank is slidably connected to the oil pipe support. An upper mold spraying head located on the upper mold support seat and a lower mold spraying head located on the lower mold support seat are arranged on the oil spraying pipe.

[0008] By adopting the above technical solution, during production, the oil spraying pipe can spray the release agent on the upper mold and the lower mold at the same time. After spraying is completed, the upper mold and the lower mold enter the automatic mold opening and closing mechanism at the same time. The turnover mechanism can turn over the upper mold to the upper side of the lower mold to facilitate subsequent locking, which shortens the production process and can effectively reduce the production cost.

[0009] Preferably, the turnover mechanism comprises a support plate and a mounting seat vertically fixed on the lower mold support base, the bottom end of the mounting seat is hinged with a first connecting rod, the lower mold support base is provided with a driving mechanism for driving the first connecting rod to rotate around the hinge point, the top end of the mounting seat is hinged with a second connecting rod parallel to the first connecting rod, the end of the first connecting rod is hinged with a third connecting rod parallel to the mounting seat, the end of the third connecting rod away from the first connecting rod is hinged with the support plate, and the end of the second connecting rod away from the mounting seat is hinged with a fourth connecting rod, and the fourth connecting rod is hinged with the support plate.

[0011] Preferably, the driving mechanism comprises a first cylinder hinged on the upper mold support base, and the piston rod of the first cylinder is hinged with the end of the first connecting rod away from the mounting seat.

[0012] By adopting the above technical scheme, the extension and retraction of the cylinder are used to drive the connecting rod mechanism to move, and then drive the support plate to turn over, and the cylinder can play a limiting role, so that the support plate can be kept stable at the starting position and the terminal position and will not move under the gravity of the telegraph pole.

[0013] Preferably, the support plate is provided with a bracket, the bracket is provided with a clamping mechanism, and a lifting assembly is arranged between the bracket and the support plate.

[0014] By adopting the above technical scheme, if the upper mold and the lower mold are directly fitted during the turnover of the upper mold, the upper mold and the lower mold may collide and be damaged, by arranging the lifting assembly, during the turnover, the lifting assembly is retracted, so that the upper mold can avoid the lower mold during the rotation, and after the turnover is completed, the upper mold is driven downward by the lifting assembly to be buckled with the lower mold.

[0015] Preferably, one side of the automatic mold opening and closing mechanism is provided with a bolt locking mechanism and a first jacking and translating mechanism for moving the steel film from the automatic mold opening and closing mechanism to the bolt locking mechanism.

[0016] By adopting the above technical scheme, the upper mold and the lower mold which have been combined can be automatically moved to the bolt locking mechanism, and then locked, so that the degree of automation is high, and manual locking of the bolt is not needed, thereby reducing the labor cost.

[0017] Preferably, the first jacking and translating mechanism comprises two guide rails arranged on the two sides of the lower mold support frame respectively, a sliding table is slidably connected to each of the two guide rails, a lifting table is arranged above the sliding table, and a third cylinder is vertically arranged between the sliding table and the lifting table.

[0018] By adopting the technical scheme, when the combined steel mold is moved from the automatic mold opening and closing mechanism to the bolt locking mechanism, the third cylinder drives the lifting platform to rise, the lifting platform lifts the upper mold and the lower mold on the automatic mold opening and closing mechanism, and then the translation of the upper mold and the lower mold is realized through the movement of the sliding table. The movement process is relatively stable and is not prone to misalignment.

[0019] Preferably, the bolt locking mechanism comprises a rack, a first conveying belt is arranged on the rack, a locking table is arranged on the rack and located on the first conveying belt, a second cylinder is arranged on the locking table, and an electric screwdriver is arranged on the piston rod of the second cylinder.

[0020] By adopting the technical scheme, during the transmission of the steel mold by the first conveying belt, the transmission is paused once every distance, the electric screwdriver is driven to descend by the cylinder, the electric screwdriver is sleeved on the bolt on the steel mold, and then the bolt is locked by the electric screwdriver.

[0021] Preferably, the electric screwdrivers are arranged in multiple groups along the length direction of the conveying belt.

[0022] By adopting the technical scheme, multiple groups of locking sleeves and electric screwdrivers can simultaneously lock multiple groups of bolts on the steel mold, so that the locking time of each group of steel film is shorter, and the production efficiency is improved.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] The oil injection pipe can simultaneously spray the mold release agent on the upper mold and the lower mold during the conveying process, the upper mold and the lower mold enter the automatic mold opening and closing mechanism at the same time after spraying is completed, the turnover mechanism can turn over the upper mold to the upper side of the lower mold, the production process is shortened, and the production cost can be effectively reduced.

[0025] The cylinder is used to drive the connecting rod mechanism to move, and then drive the support plate to turn over. The cylinder can play a limiting role, so that the support plate can be kept stable at the starting position and the end position, and will not move under the action of the gravity of the telegraph pole.

[0026] The tray can recycle the excess mold release agent, so that the mold release agent can be recycled, and the production cost is reduced. BRIEF DESCRIPTION OF DRAWINGS
