Description

Technical Field

[0001] The invention relates to the technical field of gantry frames, and in particular to a high-load-bearing gantry frame. Background Art

[0002] The gantry is a new type of small lifting gantry developed to meet the daily production needs of small and medium-sized factories (companies) for handling equipment, warehouse loading and unloading, lifting and repairing heavy equipment, and material transportation. It is suitable for mold manufacturing, auto repair factories, mines, civil construction sites, and other places where lifting is required. It is commonly used in construction to transport materials and move construction personnel up and down, realizing the mechanization of lifting. It can reduce manpower, reduce production and operation costs, and improve work efficiency.

[0003] Existing high-load-bearing gantries may have the following problems during use: deformation and distortion. Long-term heavy or uneven loads may cause the gantry frame to deform or twist. This will affect its accuracy and stability, causing deviations when performing precise operations; poor welding or material quality problems may also cause local deformation. If there are defects such as unfused welds and pores in the weld, stress concentration is likely to occur when the force is applied, resulting in local deformation. Loose connections The bolts of the bolted gantry may become loose. With the passage of time and the influence of vibration, the preload force of the bolts will gradually decrease, causing the connection to loosen. This will not only reduce the overall stability of the gantry, but may also generate noise and vibration, and even cause safety accidents. At the same time, icicles will form on the surface of the gantry frame in winter, and high-altitude icicles pose a serious safety hazard. Summary of the invention

[0004] The purpose of the present invention is to propose a high-load-bearing gantry frame in order to solve the above-mentioned problem.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: comprising two parallel slide rails, both ends of the slide rails are respectively equipped with column groups, and the outer wall of the column group is equipped with a snow removal detection device;

[0006] The snow removal detection device comprises two sets of sliding sleeves slidably connected to the column group, a knocking assembly and a hot air assembly are installed between the two sets of sliding sleeves, a first detection device for detecting looseness of the column group is installed in the sliding sleeve, a driving assembly is installed on the periphery of the sliding sleeve, a mounting block for detecting the verticality of the column group and the slide rail is fixedly installed on the outer wall of the sliding sleeve, the mounting block is arranged parallel to the slide rail, and pressure sensor probes are respectively installed at the corners of the upper end surface of the mounting block;

[0007] The column group includes a base with a pulley at the bottom, two support rods are vertically fixedly installed on the upper end of the base, a plurality of connecting rods are evenly installed between the two support rods, a cross rod is fixedly arranged between the two connecting rods, an opening for matching the cross rod and the connecting rod is opened on one side of the sliding sleeve, and the upper end of the support rod is fixedly connected to the slide rail;

[0008] In actual application, when the snow-clearing detection device of the device slides up and down on the outer wall of the column group, the knocking component knocks the cross rod and the connecting rod, thereby causing the cross rod and the connecting rod to vibrate, thereby not only breaking the icicles on the surface of the cross rod and the connecting rod in winter, but also effectively detecting the looseness of the cross rod and the connecting rod through the vibration and the first detection device. When there is snow on the surface of the cross rod and the connecting rod that cannot be shaken off, the snow is blown off by the hot air component, thereby reducing the weight of the column group, and the hot air component can heat the snow-clearing detection device as a whole, thereby preventing the snow-clearing detection device from being unusable in winter.

[0009] Further, the driving assembly includes a mounting shell fixed to the outer wall of the sliding sleeve, a motor is fixedly mounted on the outer wall of the mounting shell, a transmission shaft used to match the output shaft of the motor is rotatably mounted on the outer wall of the sliding sleeve, the transmission shaft and the output shaft of the motor are connected by mutually meshing bevel gears, rotating shafts used to match the transmission shaft are rotatably mounted on the outer walls on both sides of the sliding sleeve, an anti-skid wheel is fixedly mounted at the middle position of the rotating shaft, a rotating rod is rotatably arranged between the two sliding sleeves, a transmission group connected to the rotating rod is mounted at the end of one of the rotating shafts, and the transmission shaft and the rotating shaft are connected by mutually meshing bevel gears;

[0010] The knocking assembly includes a rotating drum rotatably mounted on the outer wall of the rotating rod, a limit block is fixedly arranged inside the rotating drum, a fixed block used in conjunction with the limit block is fixedly arranged on the outer wall of the rotating rod, a fixed rod is fixedly arranged on the outer wall of the rotating drum, a striking rod is hingedly arranged at the end of the fixed rod, and a torsion spring is installed between the fixed rod and the striking rod;

[0011] The first detection device comprises a protective shell fixed at the opening of the sliding sleeve, an airbag is fixedly installed in the middle of the protective shell, an air pressure sensor is installed inside the airbag, and an arc-shaped pressing plate used in conjunction with a cross rod and a connecting rod is fixedly installed at the end of the airbag, and the airbag can be used to seal the telescopic rod;

[0012] In actual application, the motor output shaft drives the transmission shaft to rotate, the transmission shaft drives the rotating shaft to rotate, the rotating shaft drives the anti-skid wheel to rotate, thereby driving the snow removal detection device to move up and down as a whole, and at the same time the rotating shaft drives the rotating rod to rotate through the transmission group, thereby driving the overall rise of the knocking assembly through the rotating rod. When the knocking assembly exceeds the central axis of the rotating rod, the knocking assembly hits the cross rod and the connecting rod under gravity, thereby completing the ice clearing effect. At the same time, when the cross rod and the connecting rod are hit, the cross rod and the connecting rod vibrate, and the vibration of the cross rod and the connecting rod will be transmitted to the arc pressing plate. The arc pressing plate will vibrate to change the air pressure inside the airbag, thereby judging the connection status between the cross rod and the connecting rod and the support rod.

[0013] Further, the hot air assembly includes a shell fixedly installed between two sliding sleeves, an air outlet is opened on one side of the shell, and a plurality of air inlet bins are fixedly arranged on the other side of the shell, a main shaft is rotatably installed at the air outlet end of the air inlet bin, a fan blade is fixedly installed at the middle position of the main shaft, a pulley is fixedly installed at the end of the main shaft, the pulleys are connected by belts, one of the main shafts is connected to the motor, and a heating rod is installed inside the shell;

[0014] In actual application, the hot air assembly is used to blow off the snow blocks on the surface of the cross rods and the connecting rods, thereby preventing excessive snow accumulation on the surface of the column group, which would cause the gantry frame to be overloaded.

[0015] Further, the transmission group includes an internal gear and a first spur gear fixedly connected to the rotating rod, a second spur gear and a third spur gear are rotatably mounted on the outer wall of the rotating shaft, and a one-way bearing is respectively arranged between the second spur gear and the third spur gear and the rotating shaft, and the two one-way bearings rotate in opposite directions, the third spur gear is meshed with the first spur gear, and the second spur gear is meshed with the internal gear;

[0016] In actual application, when the shaft rotates forward, the third spur gear on the outer wall of the shaft drives the first spur gear to reverse, and the first spur gear drives the rotating rod to reverse. At the same time, the rotating rod will drive the internal gear to reverse, and the internal gear drives the second spur gear to reverse. There is a one-way bearing between the second spur gear and the shaft. Therefore, the second spur gear rotates in the opposite direction to the shaft. Therefore, the second spur gear cannot drive the shaft to rotate. Conversely, when the shaft reverses, the shaft drives the second spur gear to reverse, the second spur gear drives the internal gear to reverse, the reversal of the internal gear drives the rotating rod to reverse, the rotating rod drives the first spur gear to reverse, and the reversal of the first spur gear drives the third spur gear to rotate. The third spur gear and the shaft rotate in opposite directions. Therefore, the third spur gear cannot drive the shaft to rotate. Therefore, no matter whether the shaft rotates forward or reversely, the rotating rod will reverse, thereby ensuring that the snow clearing detection device can drive the knocking assembly to hit the cross rod and the connecting rod whether it rises or falls, thereby improving work efficiency.

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

[0018] 1. When the snow removal detection device slides up and down on the outer wall of the column group, the knocking assembly knocks the cross rod and the connecting rod, thereby causing the cross rod and the connecting rod to vibrate, thereby breaking the icicles on the surface of the cross rod and the connecting rod in winter;

[0019] 2. By using vibration in conjunction with the first detection device, the looseness of the cross rod and the connecting rod can be effectively detected. When there is snow on the surface of the cross rod and the connecting rod that cannot be shaken off, the snow is blown off by the hot air component, thereby reducing the weight of the column group. The hot air component can heat the entire snow removal detection device, thereby preventing the snow removal detection device from being unusable in winter. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Reference Figure 1-9 A high-load-bearing gantry frame comprises two parallel slide rails 3, both ends of the slide rails 3 are respectively provided with column groups 1, and the outer wall of the column group 1 is provided with a snow removal detection device 2;

[0034] The column group 1 includes a base 105 with a pulley at the bottom, two support rods 101 are vertically fixedly installed on the upper end of the base 105, a plurality of connecting rods 102 are evenly installed between the two support rods 101, a cross rod 103 is fixedly arranged between the two connecting rods 102, an opening is opened on one side of the sliding sleeve 201 for use with the cross rod 103 and the connecting rod 102, and the upper end of the support rod 101 is fixedly connected to the slide rail 3;

[0035] In actual application, when the snow-clearing detection device 2 of the device slides up and down on the outer wall of the column group 1, the knocking component 205 knocks the cross rod 103 and the connecting rod 102, thereby causing the cross rod 103 and the connecting rod 102 to vibrate, thereby being able to break the icicles on the surface of the cross rod 103 and the connecting rod 102 in winter, and at the same time, through the vibration and the cooperation with the first detection device 209, the looseness of the cross rod 103 and the connecting rod 102 can be effectively detected. When there is snow on the surface of the cross rod 103 and the connecting rod 102 that cannot be shaken off, the snow is blown off by the hot air component, thereby reducing the weight of the column group 1, and the hot air component can heat the snow-clearing detection device 2 as a whole, thereby preventing the snow-clearing detection device 2 from being unusable in winter.

[0036] Further, the driving assembly 4 includes a mounting shell fixed to the outer wall of the sleeve 201, the outer wall of the mounting shell is fixedly mounted with a motor 401, the outer wall of the sleeve 201 is rotatably mounted with a transmission shaft 402 used to match the output shaft of the motor 401, the transmission shaft 402 is connected to the output shaft of the motor 401 through mutually meshing bevel gears, the outer walls on both sides of the sleeve 201 are rotatably mounted with a rotating shaft 403 used to match the transmission shaft 402, an anti-skid wheel 404 is fixedly mounted at the middle position of the rotating shaft 403, a rotating rod 204 is rotatably arranged between the two sleeves 201, a transmission group 5 connected to the rotating rod 204 is mounted at the end of one of the rotating shafts 403, and the transmission shaft 402 and the rotating shaft 403 are connected through mutually meshing bevel gears;

[0037] The striking assembly 205 includes a rotating cylinder 2051 rotatably mounted on the outer wall of the rotating rod 204, a limit block 2052 is fixedly arranged inside the rotating cylinder 2051, a fixed block 2041 used in conjunction with the limit block 2052 is fixedly arranged on the outer wall of the rotating rod 204, a fixed rod 2053 is fixedly arranged on the outer wall of the rotating cylinder 2051, a striking rod 2054 is hingedly arranged at the end of the fixed rod 2053, and a torsion spring is installed between the fixed rod 2053 and the striking rod 2054;

[0038] The first detection device 209 includes a protective shell 2091 fixed at the opening of the sliding sleeve 201, an airbag 2092 is fixedly installed in the middle of the protective shell 2091, an air pressure sensor is installed inside the airbag 2092, and an arc-shaped pressing plate 2093 used in conjunction with the cross rod 103 and the connecting rod 102 is fixedly installed at the end of the airbag 2092. The airbag 2092 can make a sealed telescopic rod;

[0039] In actual application, the output shaft of motor 401 drives the transmission shaft 402 to rotate, and the transmission shaft 402 drives the rotating shaft 403 to rotate, and the rotating shaft 403 drives the anti-skid wheel 404 to rotate, thereby driving the snow removal detection device 2 to move up and down as a whole. At the same time, the rotating shaft 403 drives the rotating rod 204 to rotate through the transmission group 5, thereby driving the knocking assembly 205 to rise as a whole through the rotating rod 204. When the knocking assembly 205 exceeds the central axis of the rotating rod 204, the knocking assembly 205 hits the cross rod 103 and the connecting rod 102 under gravity, thereby completing the ice clearing effect. At the same time, when the cross rod 103 and the connecting rod 102 are hit, the cross rod 103 and the connecting rod 102 vibrate, and the vibration of the cross rod 103 and the connecting rod 102 will be transmitted to the arc pressing plate 2093. The arc pressing plate 2093 will vibrate to change the air pressure inside the airbag 2092, thereby judging the connection status between the cross rod 103 and the connecting rod 102 and the support rod 101.

[0040] Further, the hot air assembly includes a shell 206 fixedly installed between the two sliding sleeves 201, an air outlet is opened on one side of the shell 206, and a plurality of air inlet bins 2062 are fixedly arranged on the other side of the shell 206, a main shaft 2071 is rotatably installed at the air outlet end of the air inlet bin 2062, a fan blade 2072 is fixedly installed at the middle position of the main shaft 2071, a pulley is fixedly installed at the end of the main shaft 2071, and the pulleys are connected by belts, one of the main shafts 2071 is connected to the motor, and a heating rod 208 is installed inside the shell 206;

[0041] In actual application, the hot air assembly is used to blow off the snow blocks on the surface of the cross rod 103 and the connecting rod 102, thereby preventing excessive snow accumulation on the surface of the column group 1, which would cause the gantry frame to be overloaded.

[0042] Further, the transmission group 5 includes an internal gear 501 and a first spur gear 504 fixedly connected to the rotating rod 204, a second spur gear 502 and a third spur gear 503 are rotatably mounted on the outer wall of the rotating shaft 403, and a one-way bearing is respectively arranged between the second spur gear 502 and the third spur gear 503 and the rotating shaft 403, and the two one-way bearings rotate in opposite directions, the third spur gear 503 is meshed with the first spur gear 504, and the second spur gear 502 is meshed with the internal gear 501;

[0043] In actual application, when the rotating shaft 403 rotates forward, the third spur gear 503 on the outer wall of the rotating shaft 403 drives the first spur gear 504 to rotate reversely, and the first spur gear 504 drives the rotating rod 204 to rotate reversely. At the same time, the rotating rod 204 drives the internal gear 501 to rotate reversely, and the internal gear 501 drives the second spur gear 502 to rotate reversely. There is a one-way bearing between the second spur gear 502 and the rotating shaft 403. Therefore, the second spur gear 502 rotates in opposite directions to the rotating shaft 403. Therefore, the second spur gear 502 cannot drive the rotating shaft 403 to rotate. On the contrary, when the rotating shaft 403 rotates reversely, the rotating shaft 403 drives the second spur gear 502 to rotate reversely. The second spur gear 502 drives the internal gear 501 to reverse, the reverse rotation of the internal gear 501 drives the rotating rod 204 to reverse, the rotating rod 204 drives the first spur gear 504 to reverse, the reverse rotation of the first spur gear 504 drives the third spur gear 503 to rotate, and the third spur gear 503 rotates in opposite directions to the rotating shaft 403. Therefore, the third spur gear 503 cannot drive the rotating shaft 403 to rotate. Therefore, no matter the rotating shaft 403 rotates forward or reversely, the rotating rod 204 will reverse, thereby ensuring that the snow clearing detection device 2 can drive the knocking assembly 205 to hit the cross rod 103 and the connecting rod 102 whether it is rising or falling, thereby improving work efficiency.

[0044] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
