DETAILED DESCRIPTION
[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0025] A coiled tubing vehicle flip maintenance platform, mounted on a semitrailer main beam 80, comprises a platform 10, a swing frame 20, a support rod 30, and a bolt assembly 70. The rear sides of the platform 10 and two swing frames 20 are hinged to the side walls of the semitrailer main beam 80. The two swing frames 20 are symmetrically arranged below the platform 10 to support the platform 10. The platform 10 can be flipped vertically around the hinge point, and the swing frames 20 can be flipped horizontally around the hinge point.
[0026] The pedal 10 comprises a rectangular frame 15 welded from square tubes, the top of the rectangular frame 15 is welded with an anti-slip plate 11, and the bottom forms a rectangular groove;
[0027] The swing frame 20 includes a frame 21 and a sleeve 22. The sleeve 22 is fixed to the front end of the frame 21, and the rear end of the frame 21 is hinged to the side wall of the semi-trailer main beam 80. The middle part of the sleeve 22 is a central through hole 221. The tube wall of the sleeve 22 is provided with a _-shaped slot 222 connected to the central through hole 221. The _-shaped slot 222 includes a vertical slot 2221 and a horizontal hole 2222 that are interconnected. The support rod 30 is welded by a vertical rod 31 and a horizontal pin 32. The vertical rod 31 is a cylindrical structure, which is divided into an upper section, a middle section and a lower section. The diameter of the middle cylinder 312 is larger than that of the lower cylinder 313, and the diameter of the upper cylinder 311 is the smallest. The lower cylinder 313 is provided with two upper and lower pin holes 33. The upper pin hole 33 is welded with a transverse pin 32, and the lower pin hole 33 is penetrated by the bolt assembly 70. The lower cylinder 313 of the support rod 30 is inserted into the central through hole 221 of the sleeve 22. The support rod 30 is rotated by the bolt assembly 70 to move the transverse pin 32 on the lower cylinder 313 in the vertical slot 2221 and the transverse hole 2222.
[0028] When the cross pin 32 reaches the lowest point of the transverse hole 2222 of the BU-shaped slot 222, the upper cylinder 311 is inserted into the circular hole 13 on the bottom surface of the pedal 10, and the upper surface of the middle cylinder 312 contacts the bottom surface of the pedal 10, and the pedal is in a horizontal support state; when the cross pin 32 contacts the bottom end of the vertical groove 2221 of the BU-shaped slot 222, the upper cylinder 311 is separated from the circular hole 13 on the bottom surface of the pedal 10, and the bottom surface of the middle cylinder 312 contacts the upper surface of the sleeve 22, and the swing frame 20 is rotated horizontally until it is parallel to the semi-trailer main beam 80, and the pedal 10 is flipped downward to a vertical state, and the swing frame 20 and the support rod 30 are placed in the rectangular groove of the pedal 10.
[0029] Furthermore, when the pedal 10 is in a horizontal state, two symmetrically distributed connecting ear plates 12 are welded on a long side square tube of the rectangular frame 15 close to the semi-trailer main beam, which is hinged to the pedal ear plate 40 on the side wall of the semi-tube main beam. The outer side surface of the square tube is processed with a second pin hole 14. When the pedal 20 is flipped down and in a vertical state, the pin 60 passes through the pin hole 1 on the semi-trailer main beam 80 and penetrates into the second pin hole 14 on the pedal 10 to fix the pedal 20; two symmetrically distributed circular holes 13 are processed on the bottom surface of the square tube on the other long side, which are used to connect with the upper cylinder 311 of the corresponding support rod 30.
[0030] Furthermore, a support beam 16 is welded at the middle position of the rectangular frame 15 .
[0031] Furthermore, the latch pin 60 is an L-shaped cylindrical pin.
[0032] Furthermore, the frame 21 is a trapezoidal structure formed by welding four square tubes, wherein the upper and lower square tubes are processed with coaxial pin holes 23, which are hinged to the bracket ear plate 50 welded on the side wall of the semi-trailer main beam and used as a rotating shaft; the sleeve 22 is fixed at the connection between the inclined square tube and the upper square tube.
[0033] Refer to the attached Figure 1-7 In this embodiment, the pedal 10 is an overall rectangular structure, with a rectangular frame 15 welded from four square tubes. A support beam 16 is located in the middle, and a skid plate 11 is welded to the top. Two centrally located connecting lugs 12 are welded to one long side of the square tube, which are used to hinge with the pedal lug 40 on the half-tube main beam. The outer surface of the lug is machined with a second pin hole 14. The bottom surface of the other long side of the square tube is machined with two centrally located circular holes 13 for connecting to the support rod 30. The pedal lug 40 is composed of two parallel connecting plates.
[0034] The swing frame 20 comprises a frame 21 and a sleeve 22. The frame 21 is a trapezoidal structure formed by welding four square tubes. The upper and lower square tubes are machined with coaxial pinholes 23, which are hingedly connected to bracket lugs 50 welded to the semitrailer's main beam, serving as a pivot. The bracket lugs 50 consist of two parallel connecting plates arranged vertically. The sleeve 22 has a central through-hole 221 and a jack-shaped slot 222 cut into its wall for mounting the support rod 30. The Bu-type slot 222 includes a vertical slot 2221 and a transverse hole 2222 that are interconnected. The upper end of the vertical slot 2221 is open and the lower end is arc-shaped, matching the transverse pin 32 on the support rod 30. The transverse hole 2222 is connected to the upper part of the vertical slot 2221. The width of the connecting part of the transverse hole 2222 and the vertical slot 2221 is slightly larger than the diameter of the transverse pin 32, and the diameter of the transverse hole 2222 is larger than the diameter of the transverse pin 32.
[0035] The support rod 30 is welded by a vertical rod 31 and a horizontal pin 32. The vertical rod 31 is a cylindrical structure, divided into an upper section, a middle section and a lower section. The diameter of the middle section cylinder 312 is larger than the diameter of the lower section cylinder 313 and the inner diameter of the sleeve 22. The diameter of the upper section cylinder 311 is the smallest and is the same as the diameter of the circular hole 13. The length of the lower section cylinder 313 is larger than the length of the sleeve 22. The upper section cylinder 311 is inserted into the circular hole 13 on the bottom surface of the pedal 10. The upper side of the middle section cylinder 312 contacts the bottom surface of the pedal 10. The lower section cylinder 313 has two pin holes 33. The upper pin hole 33 is welded with a horizontal pin 32. The lower section cylinder 313 is installed in the sleeve 22 of the swing frame 20. When the horizontal pin 32 reaches the lowest point of the horizontal hole 2222 of the jack-shaped slot 222, the support rod 30 is in the position of supporting the pedal 10. The upper section cylinder 311 is inserted into the circular hole 13 and serves as a limit column. The upper surface of the middle cylinder 312 contacts the bottom surface of the pedal 10, serving as a support surface, and the pedal 10 is in a horizontal working state. When the cross pin 32 contacts the bottom end of the vertical groove 2221 of the jack-shaped slot 222, the support rod 30 separates from the pedal 10. The bottom surface of the middle cylinder 312 contacts the upper surface of the sleeve 22, serving as a stopper. The swing frame 20 is pushed parallel to the semi-trailer main beam 80, and the pedal 10 is now tilted downward. The swing frame 20 and the support rod 30 are placed in the rectangular groove formed by the square tube of the pedal 10. The lower pin hole 33 is inserted into the bolt assembly 70, which not only limits the support rod 30 but also serves as a handle.
[0036] The latch 60 is an L-shaped cylindrical pin. When the step 20 is tilted down and fixed, the latch 60 passes through the pin hole 1 on the semi-trailer main beam 80 and penetrates the pin hole 2 14 on the step side to fix the step 20. When the step 20 is tilted up, the latch 60 is first removed and then the step 20 is tilted up.
