[0016] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0017] Figure 1 The diagram shown is an installation schematic of the tower crane pinning device in an embodiment of this utility model.

[0018] Figure 2 The image shown is a perspective view of the tower crane pinning device in an embodiment of this utility model. Detailed Implementation

[0019] The technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Combination Figure 1-2 As shown, the tower crane pin remover includes a bracket 100 rotatably mounted on the tower crane support 200. The bracket 100 forms a support space 101 for carrying the pin 300. After the bracket 100 rotates, it conveys the pin 300 to the required mounting hole 201.

[0021] In this embodiment, the pin is supported by the support space formed by the bracket, and then the bracket is rotated to send the pin into the corresponding mounting hole to achieve installation, which greatly reduces the installation difficulty.

[0022] Furthermore, the length of the support space 101 is less than the length of the pin 300, and the tail of the pin 300 is inserted into and abuts against the support space 101. The tail of the support space 101 is slightly tilted downward to prevent the pin from slipping off.

[0023] In this embodiment, since the pin needs to be inserted into the mounting hole, the head of the pin needs to be exposed before being inserted into the mounting hole. The required support space is shorter than the pin to ensure that the pin is inserted normally. At the same time, in order to ensure that the pin does not fall off, the support space is slightly inclined, with the head slightly upward.

[0024] Furthermore, a support space 101 is formed in the U-shaped support plate 102, and a baffle 103 is formed at the tail end of the U-shaped support plate 102, which abuts against the tail end of the pin 300.

[0025] In this embodiment, the U-shaped support plate is used to stop the pin and to support the pin.

[0026] Furthermore, a pressure plate 104 is formed on one side of the U-shaped support plate 102, and the pressure plate 104 abuts against the top of the pin 300.

[0027] In this embodiment, it is used to prevent the pin from falling off.

[0028] Furthermore, the U-shaped support plate 102 and the pressure plate 104 are connected by a first pin 105, and a first anti-detachment chain 106 is provided on the first pin 105.

[0029] In this embodiment, measures are taken to prevent the pressure plate from falling off and to prevent the first pin from falling off.

[0030] Furthermore, the end of the U-shaped support plate 102 away from the baffle 103 is rotatably connected to one end of the second bending plate 107, the other end of the second bending plate 107 is rotatably connected to one end of the first bending plate 108, and the other end of the first bending plate 108 is rotatably mounted on the tower crane support 200.

[0031] In this embodiment, the bracket is installed in sections using two bent plates and a U-shaped support plate to achieve the final rotating installation.

[0032] Furthermore, the first bending plate 108 has an internal receiving space 109, and the second bending plate 107 and the U-shaped support plate 102 are stored inside the receiving space 109 after rotation.

[0033] In this embodiment, after the pin is inserted, the entire bracket can be accommodated in the receiving space formed by the first bending plate, which reduces the space occupied and can prevent interference with other components.

[0034] Furthermore, after the first bending plate 108 rotates, the receiving space 109 covers the tower crane support 200.

[0035] In this embodiment, the opening of the accommodating space is covered by the tower crane support, which can protect the structure housed inside and prevent interference with other components.

[0036] Furthermore, the first bending plate 108 is connected to the tower crane support 200 via a second pin 110, and a second anti-derailment chain 111 is provided on the second pin 110.

[0037] In this embodiment, the first bending plate and the second pin are prevented from falling off.

[0038] Furthermore, a handle 112 is provided on the first bending plate 108.

[0039] In this embodiment, the entire support structure can be rotated.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
