[0028] like Figure 1-Figure 4As shown, the bridge span area lifting equipment is a rectangular frame, specifically including a base 1 formed by a first longitudinal telescopic beam 11 and a first transverse support beam 12. The base 1 is a square frame and is parallel to the ground. The two first longitudinal telescopic beams 11 are parallel to each other, and the two first transverse support beams 12 are parallel to each other to ensure the stability of the base 1.

[0029] The first longitudinal telescopic beam 11 can adopt the existing electric telescopic rod or hydraulic telescopic rod structure to save costs and reduce counterweight, and ensure that the telescopic distance of the bridge span seam lifting equipment is accurate and controllable. Figure 3 As shown, the first longitudinal telescopic beam 11 includes a first rod 111 and a second rod 113, the first rod 111 is provided with an opening along the length direction and a slide rail slidably connected to the second rod 113 is provided at the opening, the first rod 111 is slidably sleeved on the second rod 113, the first rod 111 is provided with a plurality of first through holes 112 at equal intervals, the second rod 113 is provided with second through holes 114 corresponding to the first through holes 112, and a bolt 115 for locking the relative position of the first rod 111 and the second rod 113 is provided between the first through hole 112 and the second through hole 114; the first rod 111 is slidably sleeved on the second rod 113 to facilitate fixing the first rod 111 and the second rod The relative position of the first rod 111 and the second rod 113 is determined by the embodiment of the present invention. Corresponding first through holes 112 and second through holes 114 arranged at equal intervals are opened on the first rod 111 and the second rod 113. When the first rod 111 and the second rod 113 slide to the corresponding positions, the bolts 115 can be used to pass through the first through holes 112 and the second through holes 114 in sequence to achieve the purpose of locking the position. In order to ensure that there is no relative sliding between the first rod 111 and the second rod 113, a plurality of bolts 115 can be set to lock the first rod 111 and the second rod 113. The first longitudinal telescopic beam 11 is set in this way. Not only can the telescopic distance of the lifting equipment of the bridge span seam area be clearly controlled, but the telescopic adjustment is also convenient and will not affect the normal movement of the lifting equipment. It should be noted that the second longitudinal telescopic beam 31, the third longitudinal telescopic beam 13, the fourth longitudinal telescopic beam 33, the fifth longitudinal telescopic beam 1311, and the sixth longitudinal telescopic beam 1161 mentioned in this article all adopt the same structure as the first longitudinal telescopic beam 11 to ensure the synchronization of the entire lifting equipment during size adjustment, ensure that the lifting equipment after size adjustment is still in a rectangular frame shape, and thereby ensure the stability of the entire lifting equipment during use.

[0030] In order to facilitate the walking of construction workers at the bridge span, and not affect the normal use of the hanger 6, Figure 1-Figure 3As shown, the base 1 also includes a third longitudinal telescopic beam 13 arranged parallel to the first longitudinal telescopic beam 11, the third longitudinal telescopic beam 13 is two and is located between the two first longitudinal telescopic beams 11, the two ends of the third longitudinal telescopic beam 13 are connected to the first transverse support beam 12 and enclosed to form a frame structure, and a telescopic connecting plate 14 for pedestrians to pass is provided between the adjacent first longitudinal telescopic beams 11 and the third longitudinal telescopic beams 13; by arranging the third longitudinal telescopic beam 13 on the base 1, the structure of the third longitudinal telescopic beam 13 is consistent with that of the first longitudinal telescopic beam 11, so that when When the length of the entire bridge span seam lifting equipment is adjusted by the first longitudinal telescopic beam 11, the third longitudinal telescopic beam 13 can also meet the telescopic conditions without affecting its normal use, and at the same time provide an installation point for the subsequent setting of the telescopic connecting plate 14; a telescopic connecting plate 14 is set between the adjacent first longitudinal telescopic beam 11 and the third longitudinal telescopic beam 13, and the telescopic connecting plate 14 only needs to be able to extend or shorten with the first longitudinal telescopic beam 11 without affecting the adjustment of the lifting equipment. Specifically, the existing telescopic plate structure as described in CN116465649U can be adopted, and the telescopic plate structure as described in CN116465649U can also be adopted. Figure 3 The two plates shown are connected by sliding rails, one plate is connected to the front half of the first longitudinal telescopic beam 11 and the third longitudinal telescopic beam 13, and a slide rail is arranged above the plate, and the other plate is connected to the rear half of the first longitudinal telescopic beam 11 and the third longitudinal telescopic beam 13, and a protrusion connected to the slide rail is arranged below the plate, so as to realize the sliding connection between the two plates, so that the telescopic connecting plate 14 can be extended or shortened with the extension and contraction of the first longitudinal telescopic beam 11, so as to meet the size adjustment of the lifting equipment of the bridge span seam area, and at the same time can provide a safe passage for construction personnel to ensure operation safety.

[0031] To prevent construction workers from falling from both sides of the telescopic connecting plate 14 when walking on the telescopic connecting plate 14, Figure 1 , Figure 2As shown, a first guardrail 131 is further provided above the third longitudinal telescopic beam 13, and the first guardrail 131 includes a fifth longitudinal telescopic beam 1311, a support rod 1312 and a vertical rod 1313 which are parallel to the third longitudinal telescopic beam 13, the height of the support rod 1312 is less than the height of the column 2, the support rod 1312 is vertically arranged at the junction of the third longitudinal telescopic beam 13 and the first transverse support beam 12, the fifth longitudinal telescopic beam 1311 is arranged at the upper end of the support rod 1312, and the vertical rod 1313 is parallel to the support rod 131 2 and are vertically arranged at equal intervals between the third longitudinal telescopic beam 13 and the fifth longitudinal telescopic beam 1311; a second guardrail 116 is arranged above the first longitudinal telescopic beam 11, and the second guardrail 116 includes a sixth longitudinal telescopic beam 1161 which is parallel to the first longitudinal telescopic beam 11, and the sixth longitudinal telescopic beam 1161 is arranged between the two columns 2, and a plurality of vertical rods 1162 which are arranged at equal intervals and are parallel to the columns 2 are arranged between the sixth longitudinal telescopic beam 1161 and the first longitudinal telescopic beam 11; by A second guardrail 116 is arranged on the telescopic connecting plate 14, and a first guardrail 131 is arranged on the third longitudinal telescopic beam 13, that is, the first guardrail 131 and the second guardrail 116 are arranged on both sides of the telescopic connecting plate 14 to prevent construction workers from falling from both sides when walking on the telescopic connecting plate 14; it should be noted that since the first longitudinal telescopic beam 11 and the third longitudinal telescopic beam 13 can slide, the vertical rod 1162 in the second guardrail 116 needs to be arranged on both sides of the first longitudinal telescopic beam 11 according to the arrangement mode of the first longitudinal telescopic beam 11, and will not fall due to the telescopic connection plate 14. The vertical rod 1162 may collide with the vertical rod 1162 due to the shrinkage. That is, when the telescopic structure in which the first rod 111 is slidably arranged on the second rod 113 is adopted, the vertical rod 1162 on the first rod 111 needs to be arranged on the outside of the first rod 111, and the vertical rod 1162 on the second rod 113 needs to be arranged on the inside of the second rod 113; the vertical rod 1313 in the first guardrail 131 is arranged in the same way; the height of the support rod 1312 of the first guardrail 131 is less than the height of the column 2, and the height of the support rod 1312 needs to be greater than half of the height of the construction personnel, usually greater than 1.2m, such a setting can ensure the height distance between the fifth longitudinal telescopic beam 1311 and the third longitudinal telescopic beam 13, that is, the height of the set upright pole 1313 can also be confirmed. At the same time, setting the support rod 1312 and the upright pole 1313 to this height can not only ensure that the construction personnel can normally pull the sling 6 on the telescopic connecting plate 14, but also ensure that the construction personnel will not cross the first guardrail 131 when pulling the sling 6 and cause a safety accident; adding the upright pole 1313 between the third longitudinal telescopic beam 13 and the fifth longitudinal telescopic beam 1311 can not only ensure the connection stability between the third longitudinal telescopic beam 13 and the fifth longitudinal telescopic beam 1311, but also prevent things on the telescopic connecting plate 14 from falling between the third longitudinal telescopic beam 13 and the fifth longitudinal telescopic beam 1311; setting the second guardrail 116 has a similar function to the first guardrail 131, in order to prevent the construction personnel from falling and causing sprains or other accidents when working or walking on the telescopic connecting plate 14, and at the same time ensure the connection stability between adjacent upright poles 2. .

[0032] In order to enhance the stability of the first guardrail 131, it is prevented that when the construction personnel approach the first guardrail 131 to pull the sling 6, the first guardrail 131 is pressed to tilt, which may cause safety hazards. Figure 1 , Figure 2 As shown, a cross bar 15 parallel to the first transverse support beam 12 is provided between the adjacent support rods 1312 on the two first guardrails 131, and the cross bars 15 are multiple and are evenly spaced along the height direction of the support rods 1312 and are arranged between the adjacent support rods 1312 on the two first guardrails 131; the two first guardrails 131 are connected together by the cross bar 15, so that the two first guardrails 131 and the cross bar 15 form a quadrilateral to enhance the stability of the two first guardrails 131, and at the same time, multiple cross bars 15 are evenly spaced along the height direction of the support rods 1312, which can not only enhance the stability between the two first guardrails 131, but also provide a protective effect, thereby protecting construction workers from falling due to the gap between the two first guardrails 131 during construction, thereby ensuring construction safety.

[0033] In order to save costs and reduce the weight of the lifting equipment in the bridge seam area, Figure 1 , Figure 3As shown, each of the longitudinal sliding mechanisms 41 includes a slider 411 and an extension 412 slidably mounted on the second longitudinal telescopic beam 31, the slider 411 is provided with a first slide groove 4111 adapted to the second longitudinal telescopic beam 31, the extension 412 is perpendicular to the second longitudinal telescopic beam 31 and is arranged below the slider 411, and the lower end of the extension 412 is fixedly connected to the connecting plate 42; the transverse sliding mechanism 43 includes a slide rail and a mounting block 431 for mounting the hanger 6, the slide rail is arranged at the lower end of the connecting plate 42 along the length direction of the connecting plate 42, the top of the mounting block 431 is provided with a second slide groove adapted to the slide rail, and the second slide groove is slidably mounted on the slide rail; a slider 411 is arranged on the second longitudinal telescopic beam 31, and a first slide groove adapted to the second longitudinal telescopic beam 31 is provided on the slider 411 to ensure that the slider 411 always slides along the second longitudinal telescopic beam 31 under the drive of the motor The first and second sliding grooves 4111 and 4113 are used to slide the slider 411 on the second longitudinal telescopic beam 31. When the slider 411 slides, it drives the connecting plate 42 connected to the slider 411 to move along the direction of the second longitudinal telescopic beam 31. A slide rail arranged along the length direction of the connecting plate 42 is arranged at the lower end of the connecting plate 42. A second slide rail adapted to the slide rail is opened on the top of the mounting block 431, so that the mounting block 431 can slide along the length direction of the connecting plate 42 under the drive of the motor. The slider 411 that can slide along the second longitudinal telescopic beam 31 and the mounting block 431 that slides along the length direction of the connecting plate 42 cooperate with each other, so that the hoisting device 6 can be moved within the range of the top hoisting frame 3 to ensure the hoisting range of the hoisting device 6. At the same time, the entire hoisting equipment can be driven to move through the walking mechanism 5 to ensure the hoisting range of the hoisting device 6, so that the hoisting equipment in the bridge span seam area can be hoisted at any position in the bridge span seam area.

[0034] Furthermore, in order to ensure the sliding stability of the sliding hoisting module 4, as Figure 1 , Figure 3As shown, the top hanging frame 3 is also provided with a fourth longitudinal telescopic beam 33, and the top hanging frame 3 is also provided with a fourth longitudinal telescopic beam 33 with the same structure as the second longitudinal telescopic beam 31, the fourth longitudinal telescopic beam 33 is arranged between the two second longitudinal telescopic beams 31 and parallel to the second longitudinal telescopic beam 31, and a longitudinal sliding mechanism 41 is slidably sleeved on the fourth longitudinal telescopic beam 33; by providing the fourth longitudinal telescopic beam 33, while being able to telescope with the first longitudinal telescopic beam 11, the connection strength between the two second transverse support beams 32 can be strengthened, and at the same time, an installation point is provided for the additional longitudinal sliding mechanism 41; in order to make the longitudinal sliding mechanism 41 also applicable to the fourth longitudinal telescopic beam 33, the fourth longitudinal telescopic beam 33 is The structural design of the beam 33 is consistent with the structure of the second longitudinal telescopic beam 31; by adding a longitudinal sliding mechanism 41, four longitudinal sliding mechanisms 41 are driven simultaneously above the connecting plate 42, which can not only ensure the connection stability between the connecting plate 42 and the top lifting frame 3, but also ensure the sliding stability of the sliding lifting module 4, and will not cause the problem of inaccurate lifting point caused by left and right deviation; the four longitudinal sliding mechanisms 41 can all be connected to the motor and driven by the motor, or only one longitudinal sliding mechanism 41 can be connected to the motor and driven by the motor, and the other three follow the longitudinal sliding mechanism 41 to slide synchronously, but due to the heavy weight of the hoisted object, in order to reduce the burden of the motor-driven longitudinal sliding mechanism 41, at least two of the longitudinal sliding mechanisms 41 need to be driven by the motor.

[0035] To ensure the connection stability between the first longitudinal beam and the column 2, and to avoid the overall deformation and instability of the bridge span area hoisting equipment due to the excessive weight of the hoisted object when using the hoisting device 6; Figure 1 As shown, the extending end of the first longitudinal telescopic beam 11 is provided with a reinforcing rib 117 connected to the column 2, and the reinforcing rib 117, the extending end of the first longitudinal telescopic beam 11, and the column 2 together form a triangle; by providing the reinforcing rib 117, and providing the reinforcing rib 117 at the extending end of the first longitudinal telescopic beam 11, it is possible to strengthen the connection stability between the first longitudinal telescopic beam 11 and the column 2, and will not affect the subsequent provision of the second guardrail 116 on the first longitudinal telescopic beam 11.

[0036] To ensure the connection stability between the second transverse support beam 32 and the column 2, when the hoisting device 6 is used, the overall bridge seam area hoisting device will not be deformed and unstable due to the excessive weight of the hoisted object. Figure 1 As shown, a triangular reinforcement plate 321 is provided between the second transverse support beam 32 and the column 2; by adding the triangular reinforcement plate 321, the strength of the connection between the second transverse support beam 32 and the column 2 is increased, thereby ensuring the stability of the entire lifting equipment.

[0037] The above-mentioned walking mechanism 5 can adopt the existing roller structure. In order to adapt to the telescopic use of the first longitudinal telescopic beam 11 and enable the bridge span area lifting equipment to achieve span telescopic use, the walking mechanism 5 is a universal wheel 51, and the universal wheel 51 is arranged below the connection between each of the first longitudinal telescopic beam 11 and the first transverse beam; by arranging the universal wheel 51 below the connection between the first longitudinal telescopic beam 11 and the first transverse beam, it can not only ensure the movement of the entire lifting equipment, but also will not affect the telescopic adjustment of the first longitudinal telescopic beam 11 to adjust the width of the lifting equipment to adapt to the normal use of bridge spans of different widths.
